hey so im going to be buying my first mac before the end of this weekend. its going to be a unibody mbp 2.4ghz! i was originally going to buy a refurb from apple.com for 1700, but i saw that macmall is offering the same thing for 1750. should i buy from apple or macmall? will i still get the 1 year applecare warranty from macmall? also does macmall charge tax?
