Hi, I'm going to buy a 17" MBP when I'm visiting the USA later this month. Obviously I'm looking for the best deal. Apple charges $2499 and will add California sales tax. Amazon seems a much better deal with $2345 and not charging sales tax. However, while at Amazon I noticed some of the other sellers there have even better prices, for example $2139. This lowest price is from a retailer with only 54 ratings (all positive). I'm not from the USA myself and have no experience with 3rd party retailers on amazon. Does amazon assess them and can they be trusted or is there a real risk of running into a scam on amazon? Saving a couple of hundreds on a MBP sounds tempting but is this one of those situations where too good to be true literally means that?
