I've been using this website lately to pass the time in class and since we have so many shopping threads on here I thought other GCers might like it too. It's a reverse auction site (the price of an item goes down over time) and they also do a cash-back program with a lot of different places (Target, GAP, Best Buy). The cash-back is really cool because you can buy stuff you'd buy anyway and save a little extra money on it. If you want to sign up you can do so
here using my referral link.
I'm not trying to seem spammy with this so sorry if I do, I just think it's a pretty cool site and a fun way to save some money.
