I gave BookCashFast a try as I like to evaluate everyone in the textbook industry. I sent them one book in very good/excellent condition with zero pages highlighted or with writing. They downgraded my quote 25% because they said the corners were banged up. Which everyone knows is common with books but it was not serve by any means. The customer service is fast to respond however have a, "we are right, the customer is wrong" approach to solutions. Therefore my rating is 1 out of 10 for their company. Stick to a real company not a pop up one that can fold at any minute.
