1. Find the book and choose an edition
A title, author or ISBN search checks public book catalogues. Matching books are displayed so you can choose the relevant edition rather than mixing every book with a similar name into one comparison.
Catalogue records may contain title, author, publisher, publication date, ISBN and a cover image. Retailer information is still the final authority for the item being sold.
2. Carry your preferences into retailer searches
The selected title and author are combined with useful filters such as binding, cover notes and language. This avoids relying only on ISBN, because marketplace sellers often omit it and an ISBN-only search can return very few results.
Amazon, eBay, AbeBooks and Vinted links are regional. The selected currency takes priority, while the visitor's country provides the initial default where supported.
3. Distinguish priced deals from retailer matches
A priced result means a price was visible in public structured retailer data or a public search result at the time of checking. It does not guarantee stock, delivery cost or the final checkout total.
A retailer match means the service found a relevant product page or prepared a precise search link, but could not reliably read a public price. It is labelled "Check site" rather than inventing a number.
4. Verify the final retailer page
Retailers change prices, stock and page formats frequently. Marketplace condition and delivery may depend on an individual seller. Always confirm the title, ISBN, language, condition, availability and full checkout total before buying.
Accounts and saved links
Guest saves remain in the current browser. An account can store saved retailer links in the cloud so they are easier to revisit. AffordThatBook does not complete the purchase; checkout takes place on the retailer's website.
Independent and free to use
AffordThatBook is an independent comparison service. The support button is optional and helps fund the project. A donation does not affect result ordering.
