MAP is a voluntarily agreement
that all legitimate manufacturer authorized retailers enter into with
their authorized USA supplier, usually the manufacturer, and in some
cases, the official USA distribution arm designated by the manufacturer.
According to such agreements, retailers can usually sell MAP restricted
items for any price they choose, but may not display in any print or
online advertising, a price below the Minimum Advertisable Price.
