I feel like there should be a place where you can see how much money you can get for your books when you sell them back to the book store. I know that last time I went there they only offered me 30 dollars for a book I paid 130 for. I was already down there so I sold it back but I know I could have gotten way more for it by selling it online. Can people start posting about how much they got for their books so other people will know whether or not it’s worth it to go down there or just sell it on their own.
I know it isn't that far to go down there, but I just feel it would be more convenient to see it online.

Back at the beginning of June, I got $55 back for my Math 112 book. It blew me away because I had purchased it from another student for only $25. Probably the only "profit" situation I'll ever have with a textbook. :)
I have no idea if they're still offering this much, but I would recommend giving it a shot!
