I sold back a Physics book for what I was told would be $31.10. When credited only $24.88, I immediately contacted BooksRun and asked for the original amount or the book back. They told me that the book wasn't in the condition indicated, which was completely false. What they didn't know was that I took pics of the book before I sent it in. When I provided the evidence that the book was in good condition, they completely stopped responding and have not provided the $6.22 difference. Why fight over such a small amount, you might ask? Because companies need to be held accountable for their unethical business practices. You don't get to keep my book and my money.
