Map enforcement is an approach from makers that directs the most reduced value their merchant or affiliate can publicize the items on the web or in promoting materials — however it doesn't uphold what value they can sell it at in physical stores or in private exchanges. For instance, the maker could remember for an agreement with an affiliate that you can't publicize this item for under $99 – or the base promoted cost. On the off chance that the merchant or affiliate showcases the item for less, the producer can end the agreement.
