2.5/5 stars
Website and order was easy to use - no problems there. Prices are fairly high for what is essentially a book that would've been sent to landfill/recycle. For example, their own book buying service offers the price of £0.43 for a book they're selling for £4.99.
Delivery was completed in an average time frame over the course of a week (disregarding the book that got lost in the post). However, books were not packaged at all except for a thin plastic bag which had ripped open on 3/4 packages. One book was so mangled that I had to get a refund - the pages were curled up and torn apart and it had damp damage and smelt mouldy.
Another book did not arrive and I had to request a replacement, so my order was not completed until almost a month after my order was placed.
Customer service was fairly responsive and were able to resolve the problems easily. For this reason the review is not 1/5.
Overall I wouldn't jump to use the service again. I wouldn't necessarily recommend others to buy from them. I would say seek out a competitor.
