I have a 2009 17 and 13 macbook pros that I want to trade in and get a new computer. I have been trying craiglslist, but just get bogus offers, so was wondering if any one has dealing with powermax? I dont want to do ebay because just to easy for someone to mail me back an empty box and say they never received it. So besides powermax, any other good trade in companies that you know of? Thanks
