Wish you could trade that heavy BioChem book you never read for something truly valuable like the collected works of Freud or maybe the Pirates of the Caribbean dvd? Thanks to SwapSimple, you can. Started by a couple of local college grads as an attempt to stick it to the publishing man, it's been going and growing online for about a year. The coolest thing is that the recipient of your BioChem book pays for that shipping and you pay for dvd shipping. Rumor has it they're servers at a local restaraunt so the $2 per order charge obviously isn't making them rich, but I bet they'd accept tips.
