I was very disappointed with this service. They are arbitrary on which books they select, offer peanuts for them (really low prices) and then took about 3 weeks to pay. They said they hadn't received the books, after a prompt, and promised to reimburse me immediately. This didn't happen, the following week the books 'had been delivered' but it took another week to get the money. The customer service was not brilliant, rather patronising, so sadly I won';t be using them again. I have a library of books to sort though so will have to send them to Oxfam or similar.
