Swap
Only on SwopseeOffer books from your shelf for the ones on your list, and add cash on either side to balance a deal. No money needed at all if the trade is even.
The UK's book swap marketplace
Swopsee is launching with books: trade your finished reads straight across, add a little cash to balance a deal, or simply buy and sell second-hand. Every trade is protected from payment to doorstep.
One marketplace
Most marketplaces stop at buying and selling. Swopsee adds a third option: trade the books you have finished for the ones on your list.
Offer books from your shelf for the ones on your list, and add cash on either side to balance a deal. No money needed at all if the trade is even.
Shop second-hand books at a fraction of cover price. Your payment is held by Swopsee until the book arrives as described, on every single order.
Scan the barcode and your listing fills itself in. When your book sells, you keep 100% of the price. Buyer fees never come out of your pocket.
How it works
Whether you are buying, selling or swapping books, every trade follows the same simple, protected path.
Scan the ISBN barcode and the title, author, cover and series fill themselves in. Add photos and condition, and you are live in under a minute.
Your book appears in search by title, author or ISBN, in genre browsing, and in the feeds of readers whose want-lists match it.
Buyers pay through Swopsee and the money is held safely until the book arrives as described.
Send it with tracked delivery. Once the buyer confirms receipt, the full price is released to you.
Add the books you are hunting for, or import your Goodreads or StoryGraph library in one upload and let it do the work.
When a match appears, offer books from your own shelf in exchange, and add cash on either side to balance the deal.
Negotiate directly with the other reader until you are both happy with the trade.
Books travel with tracked delivery. Higher-value swaps over £30 are verified at Swopsee HQ before being forwarded on.

Monthly event
One-to-one swaps need two people who each want the other's book. Shelf Swap doesn't: it links readers into chains, so every book travels to someone who actually wants it.
Tell us what you can part with and what you are hunting for. Importing your Goodreads or StoryGraph library does most of the work.
Shelf Swap matches whole chains of readers, so your book goes to someone who wants it even when they have nothing you want back.
When a loop closes on Swap Day, each person sends one book with tracked delivery and gets one from their want-list in return.
Trade with confidence
Money and items only move when both sides are happy. That is the deal, on every deal.
Your payment is held securely by Swopsee, and the seller is only paid once you confirm the item arrived as described. If it never arrives, or is not what was promised, you get a full refund.

Questions
Because a swap marketplace only works with depth. By starting with books, we can build a catalogue with real choice in every genre before opening up more categories, and give readers book-native tools like ISBN scanning, want-lists, series tracking and shelf imports that generic marketplaces don't have. More categories will follow once the bookshelves are full.
Find a book you want and make a swap offer using one or more books from your own shelf. The other reader can accept, decline, or counter-offer, and either side can add cash to balance the deal. Once agreed, both parties post their books with tracked delivery. For swaps over £30, items are routed through Swopsee HQ for verification before being forwarded.
Shelf Swap is Swopsee's monthly swap event. Instead of needing two people who each want the other's book, Shelf Swap links readers into chains: your book goes to someone who wants it, and a book from your want-list comes to you from someone else entirely. When a loop closes on Swap Day, everyone posts one book and everyone receives one. Join by having books listed and a want-list filled in before the event.
Yes. Export your library as a CSV from Goodreads or StoryGraph (both have this built in) and upload it to Swopsee. Your to-read shelf becomes your want-list, and we'll suggest books from your read shelf that you might want to list. Nothing is listed automatically; you confirm the condition and photos of anything before it goes live.
Scan the ISBN barcode with your phone and the title, author, cover art, genre and series details fill themselves in. Add your photos, pick a condition, set a price or swap value, and you're live, usually in under a minute. You can also search by title or author if the barcode is missing.
Buyer Protection is automatically applied to all purchases for a small fee. Your payment is held securely by Swopsee until you confirm the book has arrived in the condition described. If it never arrives, is damaged in transit, or is significantly not as described, you can raise a dispute within 2 days of delivery for a full refund.
Swapper Protection adds a layer of security to swaps. For swaps valued over £30 it is mandatory; under £30 it is optional. Both parcels are shipped to Swopsee HQ first, where they are verified before being forwarded to their new owners. If there is a problem with either one, both are returned.
Browsing, listing books, and basic swapping are completely free, and sellers always keep 100% of their sale price. Buyer Protection and Swapper Protection include small fees that cover secure handling, escrow, and support. There are no hidden subscription or platform fees.
When a buyer purchases your book, their payment is held securely by Swopsee. Once the buyer confirms delivery, or after the 2-day confirmation window passes, the funds are released to your connected payout account via Stripe. You keep 100% of your sale price.
Join Swopsee, list the books you've finished, and trade them for the ones on your list.
