Costco Wholesale Liquidation Auctions offers a wide range of categories of liquidation merchandise. Here’s a list of typical inventory categories sold on the Costco Wholesale Liquidation Auctions marketplace:

Types Of Liquidated Inventory

The selection, quality, and quantity of available products liquidated through the Costco Wholesale Liquidation Auctions marketplace depend on a number of factors including: returns, shelf pulls and excess inventory.

  • Member Returns
  • Inventory that was purchased by customers and returned to the store for any of a number of reasons. The quality of inventory is dependent on the amount of use by the customer before returning and whether it was damaged or worn out in the process. Typically, Member Returns product shows little to no damage.
  • Excess Inventory
  • Inventory that did not sell and is in too small a quantity to place on typical Costco displays.
  • Rare Shelf Pulls
  • Inventory that is not in sellable condition directly to customers. The merchandise may or may not be functional with missing or broken parts.

  • Like New
    • Merchandise can be unsold merchandise or shelf pulls and have never been used by a member. Items may have minor wear and tear from handling and sorting.

  • Grade A/B
    • Grade A/B can be member returns or unsold merchandise.
      • Member Returns
        • It’s not uncommon for members to return unused merchandise to Costco. Even if the member hasn’t used the item, if any portion of the packaging has been opened, it can not go back on the sales floor. This unused merchandise will be part of Grade A/B liquidation.
        • It is also not uncommon for members to return merchandise to Costco after it has been tried. Reasons for return include shipped in duplicate, buyer remorse, wrong size, color, damage during shipping, wrong item, didn’t need, didn’t work, missing part, or no reason given. After receiving from a warehouse, the Costco Returns Depot conducts a visual screening but does not test items before determining Grade. Expect that some percentage of items may be damaged, torn, missing parts, missing manuals, or otherwise incomplete/non-functional.
        • Although not a general requirement for a refund, most members do return items in the original box.
        • Member Returns can include online purchases.
      • Unsold Merchandise
        • When the inventory of an item or category of items becomes too small to mass out in typical Costco displays, warehouses may liquidate this unsold merchandise.
  • Grade C/D
    • Grade C/D lots are member returns or warehouse displays that fall below the A/B Grade standard. Items may be heavily scratched and/or dented, have missing or broken parts.
