Should different products get different Black Friday offers?

Products differ in what an offer does to them, so margin, stock, shipping cost and full-price demand decide which ones carry your Black Friday offer. Cutting everything at once hides which products earned the extra sales, since shoppers can switch between them, so a product group’s offer is judged in its own test, on that test’s profit per visitor.

If your sale puts one offer on every product, the catch is what it costs on the products that would have sold without it.

One sitewide offer is the easy default

Your Black Friday sale is planned. One offer covers every product, and one line on your banner says so.

One offer is easy to set up, run and explain to your shoppers. But a product that sells at full price gets the same discount as one that only moves once marked down. That means part of your discount goes to products that never needed it.

Your best-sellers may not need the offer

A best-seller can top your revenue list and keep little of each sale.

Say your best-seller sells at full price all year on a thin margin. An offer on it cuts that margin on sales you were already making, and at its volume a wrong call repeats on every unit.

Because best-sellers sold anyway and drew shoppers in, one Intelligems product marketer’s practice at a former brand was to give them a single-day deal outside the sitewide sale. One footwear brand’s Labor Day 2025 test points the other way: on an interim read, a light discount on its best-sellers seemed to lift sales of the rest of the range.

Neither case settles it for your store: a best-seller’s margin and full-price demand decide whether it carries the offer.

The offer can differ by product group

How you spread the offer across your catalog is part of the offer.

• One offer on every product is simple to run and to say, but every product gets the same cut.

• Setting groups at different levels under one “up to” headline keeps one message, but its top level holds for only some products.

• Holding your full-price sellers lighter or out keeps their margin, but the products shoppers came for look less like a deal.

• A separate cut for stock you need to move serves its own goal, but it adds one more offer for shoppers to read.

Each product’s limits change what a sale costs

Besides full-price demand, four limits shape what the offer costs you: margin, stock, shipping and clearance.

• If a product has margin to spare, it has room for your offer, at the cost of that margin.

• If stock is thin, a big sale can leave shoppers unable to buy what drew them. Picture a shopper tapping your sale banner for the jacket everyone wants, finding only odd sizes.

• If a product costs more to ship or ships from a slower warehouse, each extra order carries that cost or delay.

• If stock has to go, it can go in this sale or another, though a cut alone may not move it: another footwear brand put its past clearance section’s poor sales down to broken sizes.

Each limit stays a guess for your store until a group’s offer gets its own test.

More orders can still mean less profit

More orders at a lower price do not settle a cut alone. The lower price has to lift volume enough to cover the margin given up per unit, and profit per visitor shows whether it did.

In Intelligems’ customer work, a fragrance brand asked whether to cut prices on its whole line or one collection. Cutting every collection at once cannot separate real demand for one from shoppers switching from another, now equally cheap. Sorting by one collection’s buyers shows what they bought but not why, so each group needs a test of its own.

Intelligems hosts walk through how changing one product’s price can move shoppers to or from another, and why that product’s own numbers mislead; the example starts at 1:47.

Shoppers still need one sale they can read

The simplicity worth keeping is your shoppers’ grasp of the sale. A light offer spread across a wide range of products can weaken how your sale reads and push your deeper deals out of sight.

Test one product group’s offer on an earlier sale

Your decision comes down to four moves. The last two happen on an earlier sale.

1. Rank your products by what they keep, not only what they sell.

2. Mark the ones that sell at full price, run low, cost more to ship or need to go.

3. Test the group you’re least sure about with its own offer, or none, against your sitewide offer.

4. Judge it on that test’s profit per visitor, not the group’s own orders.

What a product can carry depends on your catalog, so strong brands judge each group’s offer by their own test. Intelligems can run an offer on only the products you choose, with a control group held back, and help you design and read that test. Its Black Friday planning hub covers this test among other before-sale moves.
