I've been saving up for a new MBP and once I've sold a few things I intend to have a little over a thousand dollars and enough to buy at least a 13". Since I'll be graduating soon my father has agreed to pay for half of my new MBP, so I'm pretty sure I'll be going for a base 15". I'm going out to visit him this year [he lives on the West Coast] so I've decided to just go ahead and buy it out there to make everything easier. Here is the thing though, I'd like to sell my current computer rather than take it along with me. It's a piece of crap with a battery that only lasts about an hour and a half so it wouldn't be worth taking it on the plane with me. Even so, I'd like a laptop while I'm traveling and when I get there. Since Apple has eliminated restocking fees, would it be okay for me to buy a base 13" (when they are refreshed), use it for the meantime and then exchange it in Cali for a 15" as long as it's within 14 days? Will they charge for sales tax twice or is that refunded as well (read about that somewhere, but forgot.) Anything else I should be aware of? Thanks.
