What Are Costco Liquidation Auctions?
Costco liquidation auctions are online bidding events where excess Costco inventory is sold in bulk to resellers.
Instead of discounting everything in-store, Costco moves:
Customer returns
Open-box items
Overstock inventory
Seasonal excess goods
…into liquidation marketplaces where business buyers compete via auction.
Unlike Facebook “pallet sellers,” these auctions are:
Transparent
Structured
Hosted on established platforms
Traceable to Costco inventory streams
These auctions are typically managed by third-party liquidators, most notably:
🔹 B-Stock (Costco Auctions)
Official liquidation partner for Costco
Website: https://bstock.com
Requires reseller permit/tax ID to register
Auctions are blind manifest (you get a general idea but not an itemized list)
Where Costco Returns Actually Go
Many people assume returned items go back on shelves. That’s not always true.
Returned Costco items typically go through one of three paths:
Restocked (if unopened and perfect)
Discounted in-store (clearance)
Sent to liquidation auctions
The liquidation channel is where resellers can access these goods in bulk.
This section is important because it captures:

Apparel
⚠️ Important: Most pallets are mixed condition, meaning:
Some items are new
