Boxing Day is uniquely British. While Black Friday was imported from the US and Singles’ Day from China, Boxing Day sales have been part of UK retail culture for well over a century. And despite the proliferation of other shopping events throughout the year, Boxing Day remains one of the top five online trading days for UK ecommerce.
In 2025, UK consumers spent over £3.7 billion online during the Boxing Day and post-Christmas period (26-31 December). The consumer mindset during this period is distinctive: people are at home, they have gift money and gift cards to spend, they are looking for bargains on items they did not receive as gifts, and they have time to browse. It is a potent combination for ecommerce.
But Boxing Day ecommerce is operationally different from Black Friday. It sits in a period when most teams are on reduced staffing, returns from Christmas purchases are already arriving, and the commercial objective shifts from volume-driving to clearance and margin recovery. This guide addresses those realities head-on.
Why Boxing Day still matters for UK ecommerce
There is a perception that Black Friday has diminished the significance of Boxing Day. The data does not support this. What has changed is the nature of Boxing Day trading, not its scale.
Boxing Day serves a fundamentally different commercial purpose from Black Friday. Black Friday is about driving volume on products you want to sell. Boxing Day is about clearing products you need to move. This distinction matters because it changes everything from your discount strategy to your marketing approach.
Key reasons Boxing Day matters for UK ecommerce brands:
- Gift card redemption. Approximately £6 billion in gift cards and gift vouchers are issued in the UK every Christmas. The majority are redeemed between Boxing Day and mid-January. If you sell gift cards, Boxing Day is when that revenue converts into actual product sales.
- Self-purchase with Christmas money. Cash gifts remain common in the UK, and recipients often spend that money online within the first few days after Christmas. This creates a burst of purchasing activity driven by free-spending money.
- Seasonal clearance. The commercial imperative to clear autumn/winter stock before spring ranges arrive makes Boxing Day discounting a business necessity, not just a marketing tactic. Every unit of seasonal stock sold in the Boxing Day period is a unit you do not have to warehouse, further discount, or write off.
- Customer reactivation. Boxing Day reaches customers who may not have engaged with Black Friday. Some shoppers deliberately avoid Black Friday and wait for post-Christmas sales. Others simply were not in a buying mindset in November.
For brands on Shopify, Boxing Day also represents an opportunity to convert Christmas browsers into customers. Site traffic from people checking gift suitability, researching products, and browsing wish lists begins rising on Christmas Day itself.
Clearance strategy that protects your brand
The biggest risk with Boxing Day sales is brand damage. Indiscriminate deep discounting across your entire catalogue sends a message that your products are not worth their normal price. The best Boxing Day clearance strategies are selective and strategic.
Tiered discount approach
Structure your Boxing Day discounts into clear tiers:
- End-of-line (50-70% off). Products you are discontinuing or that will not carry into the next season. These are your headline deals — the eye-catching discounts that drive traffic and create buzz. Because these products are leaving your range anyway, deep discounting does not damage their perceived value going forward.
- Seasonal excess (30-50% off). Products that over-traded or that you over-ordered for Christmas. You want to clear these to free up cash flow and warehouse space, but they may return next season, so maintain some price integrity.
- Core range (10-20% off or excluded). Your year-round best sellers should receive modest discounts at most, or be excluded from the sale entirely. These products sell well at full price — there is no commercial reason to train customers to wait for discounts.
- New season preview (full price). If your spring collection is ready, Boxing Day is a strong moment to introduce it at full price alongside the sale. This creates a clear distinction between clearance products and new arrivals, and captures customers who are looking for something fresh rather than something discounted.
Managing compare-at prices
UK pricing regulations require that any “was” or “compare at” price must represent a price at which the product was genuinely sold for a reasonable period. Ensure your compare-at prices in Shopify are legitimate and reflect actual recent trading prices. Inflated compare-at prices risk regulatory action and customer trust damage.
Communicating value, not just discount
The best Boxing Day marketing communicates the value of the products, not just the discount percentage. “Our cashmere scarf, originally £89, now £49” is more compelling than “45% off selected accessories”. Lead with the product story and let the discount reinforce the value proposition rather than replacing it.
Timing and duration: when to start and stop
The timing of your Boxing Day sale launch has shifted significantly in recent years. The traditional model of doors opening at 09:00 on 26 December is now largely irrelevant for online retail.
When to launch
Most UK ecommerce brands now launch their Boxing Day sale on Christmas Day evening or at midnight on Boxing Day. Some launch on Christmas Eve. The optimal timing depends on your audience and your operational constraints:
- Christmas Day evening (20:00-22:00). After the Christmas Day festivities wind down, consumers increasingly turn to their phones and laptops. Launching at this point captures the early-evening browsing window. This timing works well if you have automated your sale launch and do not need staff to manage it manually.
- Boxing Day midnight. The traditional online launch. It captures the most eager bargain hunters and gives you a clean 26 December start date for reporting purposes.
- Boxing Day morning (06:00-08:00). If you prefer a manual launch to ensure everything works correctly, an early morning launch still captures the majority of Boxing Day traffic. Most consumers do not start shopping seriously until mid-morning.
How long to run the sale
The most effective approach is to run your Boxing Day sale for 7-10 days, transitioning into a broader January sale. Deepest discounts and widest selection on Boxing Day itself, with progressive narrowing as stock sells through. By the second week of January, you should be returning to normal trading with only residual clearance items still discounted.
Avoid the temptation to run your sale for the entire month of January. Extended sales create discount dependency and make it harder to return to full-price trading. A clear end date creates urgency and gives your customers a reason to act sooner.
Shopify sale setup and configuration
Setting up a Boxing Day sale on Shopify requires careful configuration to ensure discounts apply correctly, compare-at prices display properly, and the transition into and out of sale mode is smooth.
Compare-at pricing
The most common approach for Boxing Day on Shopify is to use compare-at prices. Set the compare-at price to the original price and reduce the current price to the sale price. This automatically displays the discount percentage and strikethrough pricing on your product pages and collection pages.
If you have a large catalogue, updating compare-at prices manually is impractical. Use Shopify’s bulk editor, a CSV import, or an app like Matrixify to update pricing in bulk. Test the import on a small batch first to catch any formatting issues before applying it to your entire catalogue.
Sale collection pages
Create an automated collection that includes all products with a compare-at price higher than the current price. This dynamically populates your sale page as you add and remove products from the sale. Add subcollections for key categories (sale dresses, sale homeware, sale skincare) to make browsing easier.
Announcement bar and banners
Update your site-wide announcement bar to promote the Boxing Day sale. This should be configured in advance and scheduled to go live at your launch time. Your homepage hero banner should also change to Boxing Day sale creative. Prepare all creative assets before Christmas so that the launch requires minimal manual intervention.
Discount code considerations
If you are using compare-at pricing for your Boxing Day sale, be careful about stacking with discount codes. Customers may attempt to apply existing discount codes on top of sale prices. Configure your discount rules to prevent this if stacking would take margins below acceptable levels.

Email marketing for Boxing Day
Email marketing during the Boxing Day period requires a different approach from Black Friday. Your audience is in a different mindset, their inboxes are less crowded, and the messaging needs to reflect the post-Christmas context.
Pre-sale teaser
Send a teaser email on 23 or 24 December hinting at your upcoming Boxing Day sale. Keep it brief and festive. Many subscribers will see this on Christmas Day morning and it plants the seed for post-Christmas shopping. Do not send promotional emails on Christmas Day itself — it feels tone-deaf and most consumers are not in a shopping mindset until the evening.
Launch email
Your Boxing Day launch email should arrive early on 26 December — between 07:00 and 09:00. Lead with your deepest discounts and most compelling products. The subject line should be unambiguous: “Boxing Day Sale: Up to 60% off starts now” outperforms clever or subtle alternatives.
Category-specific follow-ups
On 27 and 28 December, send targeted emails highlighting specific sale categories. Segment by past purchase behaviour — send fashion sale highlights to fashion buyers, homeware deals to homeware customers. This personalisation significantly outperforms generic “sale continues” messages.
Last-chance email
If your Boxing Day sale has a specific end date, send a last-chance email 24 hours before it closes. Highlight items that are close to selling out and reinforce the deadline. This email consistently performs well because the urgency is genuine.

Capturing gift card and voucher spending
Gift card redemption is one of the most underappreciated revenue opportunities of the post-Christmas period. When a customer redeems a gift card, they frequently spend more than the card value — the average top-up amount in UK ecommerce is 30-40% above the gift card value.
Encourage redemption
Send a dedicated email to gift card recipients on Boxing Day or 27 December encouraging them to redeem. If possible, segment gift card recipients and send them curated product recommendations based on the product category the gift card was purchased from.
Make redemption easy
Ensure your gift card redemption process is frictionless. On Shopify, gift cards apply at checkout — make sure customers know where to enter their code and that the process works smoothly on mobile. Any friction in the redemption process risks losing the sale.
Upsell above card value
When a customer has a £50 gift card, show them products priced slightly above £50 alongside products at £50 or below. The psychological pull of a gift card that “almost covers” a desirable product often prompts the customer to top up, increasing your revenue per transaction.
Returns management during the sale period
The Boxing Day period coincides with the peak of Christmas returns. Managing returns efficiently while simultaneously running a sale is one of the biggest operational challenges of the post-Christmas period.
Separate returns from sale operations
If possible, create separate workflows for returns processing and sale order fulfilment. Returns should not slow down the fulfilment of sale orders, and sale orders should not create a backlog in returns processing. For brands using a 3PL, confirm their capacity for both inbound returns and outbound orders during this period.
Self-service returns
Implementing a self-service returns portal — using tools like Loop Returns or AfterShip Returns — reduces the customer service load during a period when your team is likely on reduced staffing. Customers can initiate returns, print labels, and track refunds without needing to contact your support team.
For a comparison of returns management tools, see our article on AfterShip vs parcelLab.
Returns as a sales opportunity
When processing a return, offer the customer an exchange or store credit rather than a refund. Many customers will accept store credit, particularly if you offer a small bonus (for example, £55 in store credit instead of a £50 refund). This retains the revenue within your business and encourages a future purchase.
Paid media strategy for Boxing Day
Paid media during the Boxing Day period offers good value because many advertisers have paused campaigns over Christmas. CPMs typically drop 20-30% in the days between Christmas and New Year, creating an efficiency opportunity for brands that maintain their presence.
Audience strategy
- Christmas gift card recipients. If you collect data on gift card purchasers and recipients, target recipients with product recommendations. This is a high-intent audience with money specifically allocated to spending with you.
- Black Friday non-converters. People who engaged with your Black Friday campaigns but did not purchase may be ready to buy at Boxing Day prices. Retarget them with clearance offers.
- Christmas browser retargeting. Consumers who browsed your site in the weeks before Christmas — potentially researching gifts — are a warm audience for Boxing Day. They know your products and may be ready to buy for themselves.
- Lapsed customers. The post-Christmas period is an effective reactivation window. Customers who have not purchased in 6-12 months may respond to deep clearance offers.
Budget allocation
Concentrate your Boxing Day paid budget on the 26-28 December window, when shopping intent is highest. Scale down through early January and reallocate budget to your new year campaigns. Do not spread your budget too thin across the entire post-Christmas period — the first three days generate the majority of Boxing Day revenue.
Transitioning into the January sale
The transition from Boxing Day sale to January sale should be seamless. From the customer’s perspective, it is a continuous event. From your operational perspective, it may involve different products, different discounts, and different marketing angles.
Evolving the product mix
As Boxing Day hero products sell through, replace them with additional sale items. Products that were held back from the initial Boxing Day launch can be introduced throughout the first week of January to keep the sale feeling fresh. This is particularly important for SEO — fresh content on your sale pages signals ongoing relevance to search engines.
New year messaging
Shift your marketing messaging from “Boxing Day Sale” to “January Sale” or “New Year Sale” by 1 January. The change in framing gives the sale renewed energy and gives customers who already purchased on Boxing Day a reason to return. Align new year messaging with fresh-start themes — new wardrobe, new home, new habits — depending on your product category.
Setting a clear end date
The most effective January sales have a clear end date. “Sale ends 12 January” creates urgency and prevents the sale from drifting into February. Communicate the end date clearly across your site, email, and paid media. After the sale ends, return to full-price trading immediately — do not let the sale linger.

Post-sale review and planning
After the Boxing Day/January sale period, conduct a thorough review to inform your future planning.
Key metrics to analyse
- Clearance efficiency. What percentage of your target clearance stock did you sell? Which categories cleared fastest? Which had to be discounted further than planned?
- Margin analysis. What was the blended margin across your sale period? Did your tiered discount approach protect margins on core products while clearing end-of-line effectively?
- Gift card conversion. What percentage of outstanding gift cards were redeemed? What was the average top-up amount? This data informs your gift card strategy for next Christmas.
- New customer acquisition. How many first-time customers did the sale bring in? What was their average order value compared to existing customers?
- Returns rate. Was the returns rate on sale items higher or lower than normal? This informs your discount depth decisions for next year.
Planning for next year
The Boxing Day review should feed directly into your planning for next year’s peak season. Document which products to order less of (chronic clearance items), which to order more of (items that sold out before the sale ended), and which marketing approaches generated the best return. This document becomes invaluable when planning next year’s stock buys and promotional calendar.

Boxing Day sales are a commercial necessity for most UK ecommerce brands. The stock needs clearing, the gift cards need redeeming, and the customers are ready to shop. The brands that handle it well combine efficient clearance with brand-appropriate marketing and smooth operations during a period when many teams are running on skeleton staff.
The key is preparation. Every aspect of your Boxing Day sale — from pricing to email templates to announcement bars to returns processes — should be ready before your team breaks for Christmas. If your sale launch requires more than pressing a button on Christmas Day evening, you have not prepared enough.
