Trade Center lets collectors swap inventory with optional cash adjustments.
Send an offer on mobile:
- Open a listing that allows trades (or Trade Center → find target listing).
- Tap Trade or Make trade offer.
- Select listings from your inventory to offer.
- Add cash on your side or request cash from them if the trade is uneven.
- Choose shipping size so we can quote your outbound label rate (platform fee is a flat $2.99 per party).
- Add a message and send.
On web:
- Open listing → Trade offer flow (sign in required).
- Same steps for offered items, cash, and message.
Rules:
- You can only offer listings you own and that are active.
- Cannot trade with yourself.
- One active offer per target trade pair may apply — cancel old offers before resending.
