Ratings and reviews

Great Experience!! Sent in 3 boxes of books with a few CD's/DVD's, got an email that they received them and were in the process of looking them over so I was like cool and just forgot about it and a couple days later woke up to a nice birthday surprise with a msg on my PayPal app, opened it up and bamm!! $150.00....NICE! Whole thing from the day I sent them out till being paid only took a little over a week... Hope this helps!!

(UPDATE)I had a request in with customer service and never heard anything back and did not get paid. I never received any money. First off I was only offered $8 for about 12 books, then when the books arrived my amount was lowered to $5 and some change even with the first time trade promotion code. Then my payment was supposed to be sent and I never received it. I won't trade with this place again.

App works well, but don't bother selling to this company. They lowball the heck out of their offering prices to begin with, but fine... I sent them all books in excellent condition, purchased new and put on my shelf with next to no wear. Of course the most valuable book of the lot I sent them was deemed non-purchasable when everything else was. Additionally, there is no way to have a book returned when they refuse to pay for it, they "responsibly recycle" it, which actually means they steal it.
