I used WeBuyBooks to sell books from a deceased person's estate, there were 1000s of books. I used two apps to go through them, I found that WeBuyBooks accepted some that were rejected by another app and vice versa so by using both I managed to sell more books. The total that I made was about £66. Packaging was easy, printing off the label was easy - I used 3 boxes instead of the two that were estimated by WeBuyBooks and I had to ring and get another label, this was easy too. I took the boxes to a nearby drop off point, very easy again - I think I could have had them collected too. I received confirmation that the books were being checked within a few days and then payment the next day, all books were accepted. The other app took a few days longer, rejected some of the books and the payment took longer to be received. So I'd recommend WeBuyBooks - easy to use scanner, easy to pack, send and then easy payment process. Great customer service when I needed to phone too.
