MAP Policies in E-Commerce: What Marketplaces Change

On a marketplace, the advertised price is often not a number anyone typed. It is the output of a repricer, a platform promotion, or a coupon the seller forgot about. And the name above the listing is a storefront, which is not a company you can write to.

Those two facts are what make marketplace enforcement different from enforcing against a dealer you have a contract with. Your policy does not change. What changes is who you can reach, and how you find out what the shopper is actually being shown.

When the marketplace is the seller

Check the seller named on the offer. A marketplace can host third-party sellers while also selling its own inventory. When the platform is the retailer, review its account and supply terms. Do not assume that first-party status removes every policy option.

Check how the marketplace obtained the stock and which account terms apply. Keep that evidence with the pricing review.

The storefront is not the seller

“PowerDeals Direct” is a display name. Identification starts with business registration lookups, and contact and site footprints such as shared phone numbers and return addresses. It ends with cross-referencing every storefront in your programme against the others, until five listings collapse into one company that can receive a letter.

The FTC’s INFORM Consumers Act guidance explains marketplace duties to collect and verify information from covered high-volume third-party sellers. Public disclosure has further thresholds and exceptions. Check what the listing or order record actually provides.

Prices the listing page does not show you

MAP covers the advertised price, and on a marketplace that number hides in several places.

• a platform promotion the seller was enrolled in automatically
• a coupon tile that only applies at checkout
• a bundle or multi-buy where the discount lands on your part
• a price that appears only after add to cart, which exists precisely so nothing below policy is ever displayed
• a repricer that drops below the floor overnight and comes back before business hours

The last one decides your monitoring schedule. Checks that run on weekday mornings will read a seller who discounts on Friday evening as compliant every single time.

What the platform will do, and what it will not

Keep platform complaints separate from price notices. A price below MAP does not by itself establish intellectual property infringement. Use the platform route that matches the evidence, and get legal review before alleging infringement.

Identify the seller and review the policy record before sending an approved notice. A test purchase may supply a packing slip, return address or serial number for further investigation. Confirm any proposed supplier match against the records. Have counsel review supply restrictions, then check the observed result.

Before any of that

Record which policy version the seller received and when. Authorisation status alone does not establish that history. Resolve missing records before deciding which response is available.

The service page covers how the monitoring and enforcement programme runs across marketplaces and dealer sites.

Correction, 23 September 2026: the earlier version treated first-party marketplace retail as beyond MAP enforcement. The account and applicable terms need review.
