Stop long-running discounts on Amazon: reference-price rules tighten April 23 and May 18
April 23: List Price starts requiring validation. May 18: if you spent more than half of the last 90 days on promo, the promo price can become your Typical Price. The downstream effects are bigger than the strikethrough.

If you sell on Amazon US, stop treating always-on discounting as normal operations starting in April. Leave a discount live too long and the platform will remember it as your real price.
A common misread is that strikethrough pricing is a front-end cosmetic — “as long as it shows, we’re fine.” It’s not. What’s actually being regulated isn’t whether you run a discount. It’s whether you’re selling long-term against an inflated anchor.
The headline
- After April 23, your List Price has to be something the platform can validate — not just a number you typed in.
- After May 18, if you spent more than half of the last 90 days selling at a promoted price, the system can quietly reclassify those promos as your Typical Price.
- Once price memory is rewritten, the damage extends past the strikethrough. Deal eligibility, Coupon headroom, and Prime promo slotting all get squeezed.
Why this hits so many sellers
The standard weekly promo rhythm — coupon on Monday, price discount midweek, short promo at the weekend — looks like activity on the inside. From the platform’s point of view, it reads very differently:
“You don’t actually have a ‘normal’ price. Your promo price is the normal price.”
Once the system reaches that conclusion, you lose the reference price that makes every subsequent discount feel like a discount.
Four SOP changes to make now
- Pull a 90-day real-transaction-price trace for every core ASIN — not just list price, actual sale price.
- Consolidate coupons, price discounts, and deals onto a single pricing calendar, not three disconnected tools.
- Retire the “always on promo” SKUs. Long-running promos are a trap in the new rule set.
- Before big events, protect price headroom first. Volume push second.
What this is really about
In 2026 on Amazon US, price isn’t only a margin question. It’s a system-trust question.
You’re not competing against peers on who discounts hardest. You’re competing against the platform’s own belief about what your “real price” is.
Don’t wait until strikethrough disappears, deal submissions start getting rejected, and post-click conversion softens before you rebuild price discipline. By then the memory is already overwritten.
