How do I sell my books on Webuybooks?

Hello there, I'm interested in selling my books on Webuybooks but I'm not quite sure how to go about it. Could you please guide me through the process? I'd like to know if there are any specific steps I need to follow, any fees I should be aware of, and how long it typically takes for the books to be sold and the payment to be processed. Additionally, I'm curious about the condition of the books that Webuybooks accepts and if there are any restrictions on the types of books they buy. Thank you for your help!
