Amazon's April 23 Deadline Will Strip Thousands of Sellers' Strikethrough Prices Overnight

Amazon just told every third-party seller that their List Price needs to be provable, not just plausible. Starting April 23, the company will require sellers to substantiate submitted List Prices through one of two methods: either the product was offered at that price at another retailer recently, or customers actually purchased it as the Featured Offer on Amazon at that same price.

If your List Price can't clear that bar, Amazon won't penalize your account. It'll do something worse. It'll silently remove your strikethrough pricing from the listing.

The Quiet End of the Made-Up Reference Price

For years, Amazon's reference price system has operated on a kind of honor system. Sellers submitted a List Price, Amazon displayed it with a line through it next to the "real" price, and customers saw a savings badge. The system worked if you define "worked" as generating sales. Whether those reference prices reflected reality was, in a lot of cases, a polite fiction.

This update changes the mechanism. Amazon's official reference price policy now requires that List Prices be validated against either external retailer pricing or actual Amazon purchase history. That's not "set it and forget it" territory anymore. It's "prove it or lose it."

The distinction matters because strikethrough pricing is one of the strongest conversion signals on Amazon. When a customer sees "$39.99 $59.99" they process it as a deal, whether it is one or not. Remove that visual cue and the listing looks like it's just... priced at $39.99. No urgency, no anchor, no reason to feel like they're getting anything special.

One seller on the Amazon forums put it bluntly: listings with "always on" coupons showed 15-20% lower conversion once the coupon was stripped compared to a clean static price with proper strikethrough display. The psychological machinery of a reference price is doing more work than most sellers realize.

The May 18 Change Is Actually the Sneakier One

April 23 gets the headline, but a second rule change hitting May 18 might cause more long-term damage to sellers running perpetual promotions.

Amazon is updating how it calculates "Typical Price," the reference price Amazon automatically generates from your own pricing history. Under the new methodology, if your product's price drops below its non-promotional median for more than 45 of any 90-day window, Amazon will fold all sales (including promotional sales) into the median calculation.

Translation: if you've been running a permanent 20% coupon on a product, Amazon will eventually recalculate your "typical" selling price to include those discounted transactions. Your "was" price slowly converges toward your actual selling price. The strikethrough shrinks. Eventually, it disappears.

This is aimed directly at the "always on sale" strategy that a massive number of Amazon sellers rely on. The pricing pattern where you never sell at the List Price but keep it there to anchor the perceived discount. Amazon has decided that pattern is misleading, and they're changing the math to make it self-correcting.

One detail that matters: price discounts not advertised to customers as promotions are treated as non-promotional sales and included in Typical Price. If you quietly lower your price without running it through Amazon's promotional tools, that counts against your median.

What Prime Exclusive Discounts Have to Do With This

The penalty structure has a sharp edge most coverage has missed. If your Prime Exclusive Discount doesn't have a valid reference price, the entire deal gets suppressed. Not reduced, not modified. Suppressed entirely, meaning the deal won't show at all.

For sellers banking on Prime Day (July) or back-to-school events, this creates a very specific compliance window. You need validated reference prices before you set up Prime Exclusive Discounts for summer events. And "validated" doesn't mean "I submitted a number." It means Amazon has verified that number against external data or purchase history. That verification isn't instant.

The practical risk: you plan a Prime Day promotion in June, realize in late May that your List Prices haven't been validated under the new rules, and discover you can't run Prime Exclusive Discounts until the reference price clears. By then, your competitors who cleaned this up in April are already live.

The 23-Day Audit Before the Deadline

Here's what I'd do if I were running an Amazon catalog right now. Pull every ASIN with a List Price set. For each one, answer two questions.

First: has this product been sold at the List Price on Amazon (as the Featured Offer) within the last 90 days?

Second: is this product currently offered at the List Price by another retailer you can point to?

If the answer to both is no, you have three options. Lower the List Price to something defensible. Remove it entirely and rely on Amazon's Typical Price calculation instead. Or, if you sell on your own website or another channel, actually list it at the List Price for a period before April 23 so there's a verifiable external reference.

Amazon's own guidance on List Prices says the price should be based on "recent sales data, ideally within the last 12 months." But the new rule is tighter than that. It's not about what you intended to sell for. It's about what actually happened.

For catalogs with hundreds of ASINs, this is genuinely time-consuming. But the conversion rate drop from losing strikethrough pricing across your catalog isn't a slow leak. It happens the day the display turns off. If you've watched how Google's own platform control changes play out, you know that waiting until enforcement day to discover the problem is a reliably expensive mistake.

Three Weeks of Comfortable Ignorance Left

Most Amazon sellers haven't seen this announcement yet. The ones who run PPC and pricing seriously will find it in their Seller Central dashboard eventually, probably around April 15 when it's too late to fix everything. The sellers with 50+ ASINs and inflated List Prices are looking at a quiet, catalog-wide conversion drop that won't show up in any single metric. It'll just look like a bad month.

I think the bigger question is whether Amazon keeps tightening after this. The direction is clear: they want reference prices that reflect reality, not aspiration. If your pricing strategy depends on the customer believing in a number that doesn't exist anywhere in the market, that strategy has an expiration date. April 23 is just the first one.
