Buying and watching need a free account. Verification happens at checkout, not before.
How you're protected
1–2 of 5
Buyer protection on every order
Your payment is held by Closo, not the supplier. Support steps in if a lot isn't as described.
How it works
First order money-back
Your first order is backed by Closo — refunded as account credit if it isn't right.
Guarantee terms
5 business days to inspect
After delivery you have 5 business days to check the lot and raise an issue before anything is released.
How acceptance works
Funds held until you accept
Your money sits with Closo from checkout until your window closes. The supplier is paid after — never before.
How escrow works
Freight quoted by ZIP, before you pay
Pallet lots ship freight: the exact cost for your ZIP is quoted at checkout. Parcel lots show postage up front.
