Minimum Advertised Price (MAP): What Sellers Need to Know

Minimum advertised price, or MAP, is the lowest price a brand allows a reseller to publicly display for a product. It doesn't control what you actually charge at checkout, only what you're allowed to advertise. If you've ever gotten an email from a supplier laying out a pricing floor for a product you carry, that's a MAP policy, and understanding what it does and doesn't restrict matters before you assume you've broken a rule you haven't.

Why Your Supplier Cares What You Advertise

Most Zorin merchants encounter MAP from the other direction than you'd expect: not as the brand writing the policy, but as the seller who received one. A supplier sets a MAP floor to stop resellers from racing each other to the bottom on the same product, which would otherwise erode the brand's perceived value and everyone's margin at once, including yours. One brand that launched a MAP policy and directly contacted violators reduced violations by more than 80% within three months, a real illustration of how much unpoliced advertised-price competition can otherwise creep in.

The distinction that trips people up: MAP restricts what you publicly display, not what a customer actually pays. A $50 MAP floor doesn't mean you can't sell the product for $42 in a private email offer, a loyalty discount, or a cart-level coupon that isn't visible on the product page itself. It means the advertised, publicly visible price can't show $42.

What You Can and Can't Do Under a MAP Policy

MAP and MSRP get used interchangeably in casual conversation, but they're not the same restriction. MSRP is the manufacturer's suggested retail price, a non-binding recommendation for what you actually sell at. MAP is a floor specifically on your advertised price, and unlike MSRP, violating it typically has real consequences spelled out in your reseller agreement.

The legal basis matters too, because "is this even enforceable" is usually the first real question once a MAP policy shows up in your inbox. In the US, MAP policies are generally legal under what's known as the Colgate Doctrine, from United States v. Colgate & Co. (1919), which established that a manufacturer can unilaterally set and enforce pricing terms with resellers without it counting as illegal price-fixing, as long as the policy is applied independently and enforced the same way against every reseller. That last part is not optional. A brand that enforces MAP against one reseller and lets another slide opens itself up to a discrimination claim, which is exactly why well-run MAP programs document every notice and apply the same escalation path to everyone.

What Happens If You (or a Competing Reseller) Violates MAP

Consequences are rarely instant termination on a first violation. A typical enforcement sequence starts with a written notice, often giving 24 to 48 hours to correct the listed products before anything further happens, and escalates only if the pattern continues.

Stage	What Happens	Typical Timeline
First notice	Written warning listing the specific product(s) and the correction expected	24-48 hours to comply
Continued violation	Loss of co-op advertising funds, promotional support, or preferred order status	Documented, applied uniformly
Repeated or unresolved	Suspension of product supply, or termination of the reseller relationship	Brand's discretion, per the written policy

The same protection cuts the other way too. If a competing reseller is undercutting the advertised price you're both bound to, you're generally entitled to report it, and a brand with a well-run program should apply the same notice-and-correct process to them that it would to you.
