Trade flow

Six steps, every one tracked

Nothing ships until both sides have agreed, and nobody gets paid until the book arrives as described.

  1. 01

    List

    Mark books in your collection as available and add the ones you're hunting for.

  2. 02

    Offer

    Propose a swap. Mix books from both sides and add a cash top-up if the values don't line up.

  3. 03

    Accept & pay

    Once accepted, any top-up is charged and held. Book-for-book swaps skip this step.

  4. 04

    Ship

    Both sides get a packing checklist and upload tracking within 72 hours.

  5. 05

    Confirm

    When your book arrives, confirm it matches. Funds release; otherwise they auto-release after 14 days.

  6. 06

    Rate

    Leave a rating so the next collector knows who they're dealing with.

Fees, worked through

What a trade actually costs

Say your book is worth a bit less than theirs, so you add $40 to even it out. The fee only touches that $40.

Exchange FAQ

Common questions

If tracking isn't uploaded within 72 hours, the trade is cancelled and any top-up is refunded. Repeat no-ships lead to account strikes.

Open a dispute before confirming receipt. The trade is frozen, an admin reviews both sets of photos, and top-ups are refunded where the claim holds up.

Cash top-ups are paid out through Stripe, so sellers receiving money go through a one-time identity check with Stripe. Book-only swaps don't need it.

Yes, any time before the other person accepts it. After that, a trade only unwinds through a missed shipping deadline or a dispute.
