Volume discount campaigns (VOLUME)

Sellers are regularly invited to participate in different website campaigns. The main characteristic of this type of campaign is that a discount is applied when a given number of product items is reached. For example, “Get 4 Pay 3,” “2x1,” or “second item at half price”. Besides Mercado Libre assumes a percentage of the offered discount. If you received an invitation and want to join, use the resources below.

      Edit items

      Since prices cannot be changed directly, follow the steps below to change the price of an item included in a volume discount campaign.

      • Delete the item from the campaign
      • Change item price just like regular price synchronization
      • Add the item back to the campaign

      • Nota:
        - Since items included in volume discount campaigns (marketplace campaign) have no fixed price, when the price of an included item rises, it will be automatically removed from the offer and you will not be able to add it back.
        - We recommend checking if the item is participating in a volume discount campaign before making (manual or automatic) price changes.
