For most small brands, a Prime Exclusive Discount is the simplest way into Prime Day or Prime Big Deal Days: you set a discount percentage, a minimum discounted price and a number of units, and Prime members see the deal price against a reference price. Pick the deepest discount that still leaves profit after the referral fee, FBA fee, landed cost and Amazon’s deal fees, raise ad budgets for the event, and make sure inventory is checked in before Amazon’s deadline.
For most small brands, a Prime Exclusive Discount is the simplest, lowest-risk way into Prime Day or Prime Big Deal Days. You choose a discount percentage, a minimum discounted price and how many units to commit, and Prime members see your deal price against a reference price. The trick is picking a discount that still makes money after Amazon’s deal fees and the extra ad spend, then making sure your inventory is in place before the event starts.
Prime Exclusive Discounts vs. Lightning Deals vs. coupons
Amazon offers several promotion types around big events. The three most small brands consider:
| Prime Exclusive Discount | Lightning Deal | Coupon | |
|---|---|---|---|
| Who sees it | Prime members | All shoppers, with Prime early access at times | All shoppers, or a targeted group |
| How long it runs | The whole event (or the dates you choose) | A few hours, until time or units run out | The dates you set, until the budget runs out |
| Where it shows | Your listing and search results, with a Prime deal badge | The deals page and your listing | Search results and listing, with a “clip coupon” badge |
| How hard to get | Fairly easy if you have a valid reference price | Stricter eligibility; Amazon recommends which ASINs qualify | Easy |
| Fee structure (as of September 2026) | Upfront fee plus a percentage of discounted sales | Upfront fee plus a percentage of deal sales | Small upfront fee plus a percentage of coupon sales |
At the time of writing, Amazon’s Prime event price discount for its October 2026 event carried a $100 upfront fee plus 1.5% of discounted sales. Lightning Deals and Best Deals had a similar structure for the same events. Coupons have used a smaller upfront fee plus a percentage of coupon sales since mid-2025. Fees change between events, so check the fee that Seller Central shows you before you submit. It’s on the submission screen.
Which one should a small brand pick?
- Start with a Prime Exclusive Discount on your best seller or two. It runs for the whole event, you control the floor price, and it’s the easiest to qualify for.
- Add a Lightning Deal if Amazon recommends one for your ASIN and you have the stock. The deals-page placement can drive a spike in sales.
- Use a coupon for products that don’t qualify for deals, or for a smaller, cheaper nudge outside the big events.
How does a Prime Exclusive Discount work?
You create it in Seller Central under the promotions area (search “Prime exclusive discounts” in Help if you can’t find it). When we submitted ours for October 2026, we set three things for each product:
- Discount percentage. How much off the price Prime members get.
- Minimum discounted price. A floor. If your regular price drops for some reason, the deal price won’t go below this. Set it above your break-even price.
- Units committed. How many units you’re offering at the deal price.
Amazon then checks eligibility. The biggest one is the reference price.
What reference price do shoppers see?
A Prime Exclusive Discount needs a valid reference price, such as a “was price” or list price, to show a strikethrough and the savings. If your product doesn’t have one, Amazon suppresses the discount and shoppers never see it.
Amazon has tightened these rules over time. Reference prices must reflect prices you’ve actually sold at, and event deals usually need to be at or below your recent lowest price. As of September 2026, the details are in Seller Central Help. Search “reference price” and “Prime exclusive discounts.” In practice:
- Don’t raise your price in the weeks before the event. It can break your reference price and look like a fake discount.
- Avoid running a deeper coupon or sale right before the event, because it can lower the price your deal has to beat.
- Check the listing the day the event starts to confirm the strikethrough and badge appear.
How do you pick a discount that still makes money?
Work backward from your true profit per unit, not from what competitors are doing. For example, take a $30 product with a $5.00 FBA fee and $9.00 of landed cost and other per-unit costs. Assume a 15% referral fee, the $100 upfront fee spread over 400 expected deal units, and 1.5% of discounted sales. These are round, made-up numbers to show the math:
| No deal | 20% off | 30% off | |
|---|---|---|---|
| Price | $30.00 | $24.00 | $21.00 |
| Referral fee (15%) | −$4.50 | −$3.60 | −$3.15 |
| FBA fee | −$5.00 | −$5.00 | −$5.00 |
| Landed and other costs | −$9.00 | −$9.00 | −$9.00 |
| Deal fee (1.5% of sales) | $0 | −$0.36 | −$0.32 |
| Upfront fee ($100 ÷ 400 units) | $0 | −$0.25 | −$0.25 |
| Profit before ads | $11.50 | $5.79 | $3.28 |
| Break-even ACoS | 38% | 24% | 16% |
In this example, a 20% discount halves profit per unit. You’d need roughly twice the sales just to make the same money. A 30% discount leaves very little room for ads. And the price at which profit hits zero, about $17 here, is where your minimum discounted price should stay well above.
A deal can still be worth running at a thin margin: it can bring new customers, reviews and a sales-rank boost that lasts after the event. But make that a choice, and know the number going in.
How should you set ad budgets during the event?
Traffic and competition both go up during Prime events. Clicks usually get more expensive, and campaigns can run out of budget early in the day, which means you miss the evening shoppers.
- Raise daily budgets on your deal products before the event. Watch them the first morning and top up campaigns that run out.
- Use your deal-day break-even ACoS, not your normal one. In the example, it drops from 38% to 24%, so bids that were fine last week may now lose money.
- Don’t cut ads the moment the event ends. Sales often stay elevated for a few days afterward. Then bring budgets back down.
- Judge the event on total profit, not ACoS alone. Our ACoS vs. TACoS guide explains why.
How should you plan inventory for a Prime event?
Amazon sets inventory deadlines before each event, and shipments that aren’t checked in by then may not be available for the deal. Deadlines are earlier than you’d think, and receiving slows down in the run-up.
- Estimate the lift. Use last year’s event if you have it. If not, plan conservatively and keep backup stock at your 3PL or prep center.
- Commit only units you can cover. Running out mid-event wastes the deal and can hurt your ranking.
- Keep stock after the event. Leave enough for the normal weeks that follow, plus the post-event bump.
- Work back from the deadline using your full lead time. Our FBA reorder point guide shows how to count every step.
A simple Prime event checklist
- Pick one or two products with a valid reference price and healthy stock.
- Calculate profit per unit at two or three discount levels, and set your minimum discounted price above break-even.
- Submit the Prime Exclusive Discount before Amazon’s deadline and note the fee shown.
- Get inventory checked in before the event’s inventory deadline.
- Hold your regular price steady in the weeks before.
- Raise ad budgets, set bids for the event’s break-even ACoS, and check both on day one.
- After the event, compare total profit with a normal week and write down what you’d change.
Shelfmate models your profit at each discount level, gives you the exact settings to enter (including a minimum price above break-even) and schedules ad budgets up for the event and back down after. You submit the deal yourself in Seller Central, and nothing that spends money happens without your OK. More on the deals page.
Frequently asked questions
How much does a Prime Exclusive Discount cost?
At the time of writing, Amazon charged a $100 upfront fee per Prime event price discount plus 1.5% of discounted sales for its October 2026 event. Fees change by event, so check the fee shown in Seller Central before you submit.
Is a Prime Exclusive Discount better than a Lightning Deal?
For many small brands, yes. A Prime Exclusive Discount runs across the event on your listing and is easier to qualify for, while a Lightning Deal runs for a few hours with a fixed quantity and more visible placement on the deals page, but has stricter eligibility.
What discount should I offer on Prime Day?
Offer the deepest discount that still leaves you a profit per unit after fees, landed cost and the extra ad spend you expect. Work backward from your profit per unit rather than copying competitors’ percentages.
Why isn’t my Prime Exclusive Discount showing?
The most common reason is that your product has no valid reference price, so Amazon suppresses the discount. It can also happen if your price rose before the event, your offer lost the Buy Box, or you ran out of stock.
Can I use a coupon and a Prime Exclusive Discount together?
Amazon has rules about how promotions stack, and those rules change. Check the promotion stacking settings in Seller Central before the event, and calculate your profit as if both apply.
