The Exchange is peer-to-peer: you list, buyers bid, and you settle directly with the winner. We review every application before a seller account goes live. A few things to know before you apply: every sale carries a flat $5 listing fee plus 5% of the winning bid, charged to you when a lot sells. Shipping is mandatory and expedited-only — 2-day ($30) or overnight ($50), picked by the buyer at bid time — and that charge passes to you in full. You're responsible for confirming that selling and shipping what you list is allowed where you and your buyer are located; RYZA doesn't clear this for you, it's on the seller, per listing.
