Condition of Merchandise sold on Costco Liquidation Auctions

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.


Costco warehouses sort all member returned merchandise to ensure only items with at least 75% of the original wholesale value are categorized as Grade A/B.  After receiving from a warehouse, the Costco Returns Depot conducts a second visual screening before determining Grade.


Although not a general requirement for refund, most members do return items in the original box.


Member Returns can include online purchases.  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.


Unsold Merchandise

When inventory of an item or category of items becomes too small to mass out in typical Costco displays, warehouses may liquidate this unsold merchandise.


On occasion, warehouse displays can be liquidated.  If the display has 75% or more of its original value it will be categorized as Grade A/B.


Grade C/D

Grade C/D lots are member returns or warehouse displays that fall below the A/B Grade standard.  Grade C/D merchandise has an estimated 74% - 50% of its original value.  (At least half the original value yet not enough to be considered A/B quality.)


Items may be heavily scratched and / or dented, have missing or broken parts.


Salvage Grade

Merchandise may or may not be functional.  Missing or broken parts are highly likely.  Merchandise quality falls below C/D Grade standards.
