I need to buy an iTouch 3G, but I have not started to shop around. I'm thinking that I should be able to find a good deal since they are being cleared out. I don't have 4 hours to spend shopping for prices, so help me out... What is a good way to get a bargain on an iTouch 3G? I prefer to buy a new iTouch, but would consider buying used from a highly reputable source. (Thanks in advance.)
