I sent two textbooks to Cash4Books. Each was the latest edition and in perfectly good condition (no markings whatsoever, no labels, no folded pages, nothing!). Based on the ISBNs, they quoted me above $60 for the two textbooks. That was quite a bit lower than what Amazon sellers were selling their used textbooks for, but I don’t know how to sell to the Amazon booksellers. So I printed out the mailing labels and sent the books off, perfectly packaged as they instructed. Three weeks later, I still haven’t received a check but I looked at my account they set up. They are showing that they will pay me $13.62 for the two textbooks. One of them costs over $75 on Amazon when sold used. So you know they will make a hefty profit off of my textbooks. Shipping did not cost that much. Plus they quoted a much higher price (still nowhere near what the textbooks were worth used). If the textbooks were in bad condition, I could understand. BUT THEY WERE IN PERFECT CONDITION!
