Hi,

This question was posted a while ago.
World of Books buys directly from charities, taking the titles they don't want or haven't got space for. So as well as preventing the destruction of perfectly good books, our customers are helping to support good causes too. We are constantly learning and improving. If you want to read more about us you can here - https://www.worldofbooks.com/en-gb/about-us

Thanks, World of Books

I'd try ThriftBooks, where I've made several purchases and had zero problems unlike WorldOfBooks where I'm still going round and round with allegedly shipped merchandise that the Postal Service has never seen.

No ‍ the books on this website are very reasonably priced, and in my experience, you won't find better service anywhere else.
The only option I can this of for cheaper books is your local library
