Black Friday promotions: stop paying for demand you already have

Shopify merchants did $14.6 billion over Black Friday weekend 2025. 81 million people bought something. Demand: not the problem.

The problem is that most brands respond to "customers are already showing up to buy" by spending as much as possible trying to get customers to show up and buy.

Black Friday 2026 falls on November 27, Cyber Monday on November 30. The pressure to run a promotion is enormous. The pressure to make it deeper, louder, and more generous than everyone else's is somehow even larger. Here's the thing worth sitting with before you set that discount percentage: when millions of customers already want to buy, the question is how much of that demand you actually need to pay for. Usually, less than you think.

Mistake one: subsidizing purchases that were already happening

Picture a Black Friday report: 10 000 redemptions on a 30% off campaign. Great screenshot for the Monday meeting!

Now look one layer down. Of those 10 000 customers, around 6 000 were buying regardless of the offer. Another 2 000 only needed something close to 10% to convert. The remaining 2 000 genuinely required the full 30%. You sent 30% to all of them.

That's the high-intent trap. Black Friday is the single best moment of the year for demand and demand is already there, which means your discount does less incremental work per dollar than it would at any other time.

Mistake two: paying full price for something that costs less

Once you start measuring incrementality, a useful question surfaces: if some customers respond to 30% off and some would have responded to 10%, why are you charging yourself for the difference?

Push that further: some customers don't need a percentage off at all. They need to feel like they got something. Those two things are not the same, and confusing them is expensive.

Walmart gave Walmart+ members 5 hours of early online access to its 2025 Black Friday events, a head start. When inventory is genuinely at risk of selling out, being first can matter more than saving another 10%. Your most loyal customers already trust the brand. Some of them may respond perfectly well to access, certainty, or exclusivity, none of which cost you margin.

Sephora found a middle path: 25% off orders above PLN 149, with brand exclusions, product exclusions, and no stacking with other offers. The minimum spend forces a real behavior change (add something to qualify) rather than handing the discount to whoever was already checking out.

Mistake three: making three good decisions that compound into one bad one

Let's say you've fixed the first two problems. You've got holdout groups running, you're differentiating by value format, your minimum spend threshold is doing real work. Then you run all of it at once on the same order.

Target's 2025 holiday strategy layered daily deals, weeklong promotions, personalized Circle discounts, early access for Circle 360 members, a price-match guarantee, and in-store giveaways. Each one makes sense in isolation, but then several of them land on the same cart.

A product markdown looks fine. A personalized discount seems reasonable. Free shipping feels fair. A loyalty reward will probably be okay. Add them together and suddenly finance would like to have a conversation that marketing wasn't planning to have until January.

Stacking rules, exclusions, discount ceilings, and campaign budgets aren't operational housekeeping. During Black Friday, they're the margin strategy.

Mistake four: confusing a transaction with a relationship

This is the one that shows up in December. Black Friday acquisition looks great in the report until your new customer turns out to be extremely loyal to 40% off and nothing else.

Any customer brought in through a deep seasonal discount has a predictable problem: the incentive was the event. Once October ends, so does the reason they came. Retention for event-acquired customers tends to be meaningfully worse than for customers acquired through product-first messaging.

Kohl's ran a Holiday Quest for $1 million in prizes, daily play, bonus entries tied to receipt scanning, Kohl's Cash. JCPenney gave qualifying shoppers a Golden Tote containing a coupon book with offers spread across eight weeks. Completely different mechanics, same instinct: use the first transaction to create a reason for the second one.

What to actually do with this

Work backwards from the behavior you want. Don't start with "what should our Black Friday offer be?" Start with what you need customers to do: bigger baskets, first purchase from a lapsed segment, moving a specific category, turning a one-time buyer into a December customer. The behavior gives the incentive a job.

Then decide what the cheapest form of value is that accomplishes it. A 20% discount, $20 off $100, a free gift, early access, and BOGO don't cost the business in the same way even when customers perceive them as similarly valuable. Run the comparison before you commit to a format.

Then set the rules before the traffic arrives. Product exclusions, stacking limits, per-customer redemption caps, budget ceilings, eligible channels. Decide all of this before November 27th!

Then leave room to move. If an offer is underperforming by Saturday afternoon, stop it. If a segment is responding at a smaller incentive, reduce the value. Black Friday is too fast for a campaign that becomes untouchable at launch.

Summary

There will still be big discounts, BOGOs, loyalty perks, free gifts, and everything else November has learned to throw at a checkout. The question is whether those incentives are attached to behavior you genuinely need to change or just collected by customers who were already reaching for their wallets.

Black Friday doesn't need help generating demand. It needs better decisions about how much of that demand is worth paying for, in what form, and what you're going to do with those customers once the weekend is over.
