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.

  • 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.

Expect that some percentage of items may be damaged, torn, missing parts, missing manuals, or otherwise incomplete/non-functional.
