The only problem I have with Amazon and Ebay is shipping time. Sometimes you don't need the book and you don't know until your first day or vice-versa. I mean there are already lots of ways to do it...Craigslist, Ebay, Amazon, etc. I was thinking more of like a trading deal of some kind. I don't even know how it would work. I'll Google the local one.
Dan said there was one for Ga Tech when he went. More of what I am talking about – an exchange.
