I've been in the market for a Macbook Air 13", and last night I spotted a Like New one from a third-party seller on Amazon for $554 + free shipping. I almost sprung for it, but I was always raised to believe that if it sounds too good to be true then it probably is. Even with Amazon's buyer protection $554 was too much a gamble for me. So what do you think... did I miss out on a terrific deal or do you think there was something shady with the seller? He was a brand new seller with no rating, and a lot of the electronics he was selling were like new items and half or nearly half off prices.
