Hi. Im very much in the middle between a MBP & MBA and I'm looking for a place where I can buy one of these (probably the MBA) and if doesnt fit my needs etc. I can easily exchange it for a MBP no questions asked. So I'm looking for a place that usually has the best price and the best no questions exchange policy and preferably tax free but if not its alright. Usually from people who had experience with exchanges. Thanks in advance.
