Some liquidators sell manifested pallets at auction. Auctions open without much notice; you can leave an email to be told once, when one opens.
Watching, bidding, winning
Watching is open to everyone, with no account and no card.
Bidding needs a free account and a card on file. The card is held at your maximum bid and never billed to bid.
Winning: you are charged at the price the lot closed at, and the order settles like any order on Closo, with the same buyer protection. Lose the lot and nothing moves.
Do not want to wait on an auction? The catalog carries lots from the same liquidators, with the same manifests and the same protection, that you can buy outright.
