Planning Your Prime Day Assortment: Which Products to Feature, Discount, and Hold Back

Most sellers approach Prime Day as a single question — how deep should the discount be? — when the decision that actually drives the outcome is which products go on the deal table in the first place. A great assortment plan puts your discount budget behind the SKUs that reward it, leaves your strong sellers at full price, and refuses to fund products that can't profit at a discount. Get the assortment right and a modest discount outperforms a deep one spread across the wrong products. Here's how to build the plan.

Sort your catalog before you set a single price

Start by putting every candidate product into one of a few clear roles for the event. This is the step that turns a vague 'let's run some deals' into a plan you can defend.

• Hero deals — discount-responsive products with strong reviews and enough margin headroom to profit at a meaningful discount. These get your deepest stock and your best deal placement.
• Traffic builders — recognizable items where a visible discount pulls shoppers into your storefront, who then buy other things at full price.
• Full-price holds — products that sell well on their own and don't need a discount; keep them at full price to protect margin.
• Do-not-deal — items with no margin headroom at a discount, weak reviews that won't convert the surge, or thin inventory you can't back. Keep these off the table entirely.

Set discounts by what each product can actually afford

A discount is only smart if a profitable net survives it. For each hero deal, work out the floor: the lowest price at which referral fees, fulfillment, your landed cost, and any deal fee still leave you a margin you're willing to accept. Set your event price above that floor, not at it — you want headroom, not a break-even stunt. The discount that looks impressive in the deal badge but nets you nothing isn't marketing; it's a donation. Different products have wildly different headroom, so resist the urge to apply one blanket discount across the assortment.

Match inventory to the role you've assigned

Your hero deals need depth — selling out early caps revenue and can stall the rank you built during the surge. Traffic builders need enough to last the event so the storefront stays compelling. Full-price holds just need normal coverage. And the do-not-deal items don't get any special inventory treatment because they're not part of the event. Mapping inventory to role keeps you from the classic failure of stocking deep on a product that wasn't going to pop and running dry on the one that was.

Build a coordinated storefront, not a pile of disconnected deals

Shoppers who arrive for one deal often buy more if the path is obvious. Group your event products in your brand store, cross-link complementary items, and make sure your hero deals point to full-price companions. The point of a traffic builder is to bring shoppers in; the point of the surrounding assortment is to raise the basket. A coordinated set of listings turns a one-item discount into a multi-item order, which is how you recover the margin you gave up on the deal.

Decide your post-event move in advance

The event ends, but its effects don't. Returning your hero deals to full price too abruptly can cause a sales cliff; a small step-down can ease the landing. Watch the rank lift you earned and decide whether a short follow-on promotion is worth holding momentum. Planning the exit before the event starts keeps you from making panicked pricing moves in the days after, when the data is still settling.

Frequently asked questions

How many products should I put on deal for Prime Day?

Fewer than you'd think. Concentrate your discount budget on a handful of true hero deals plus a few traffic builders, and leave the rest at full price. Spreading shallow discounts across your whole catalog dilutes the margin without creating a compelling reason for shoppers to act. A focused assortment with depth behind it beats a wide one stretched thin.

Should every deal have the same discount percentage?

No. Each product has different margin headroom after fees and landed cost, so a flat discount across the assortment overshoots on some items and undershoots on others. Set the discount per product against its own profit floor — deep enough to register as a real deal, but never below the point where the net turns unprofitable.
