Frequently asked questions
What is the buyer's premium?
A percentage added to the hammer price and paid by the winning bidder. On Premier, the buyer premium varies by membership tier — buyers on higher tiers pay a lower premium.
How is the seller fee calculated?
The seller fee is a percentage of the hammer price and is deducted from the seller's payout after verified delivery. Freight passed through to the seller is not fee-bearing.
Can I lower my fees?
Yes. Upgrading your membership lowers your seller fee and buyer premium immediately on your next transaction. Compare tiers with the Seller Proceeds calculator to see the breakeven point on the monthly membership cost.
Do fees apply to Buy It Now, offers, and RFQs?
Yes. Any accepted price on the platform — auction hammer, Buy It Now, accepted offer, or accepted RFQ — is subject to the same fee schedule as your membership tier.
Common use cases
