I, like many people, am on a budget, so timing is important. Right now, if I buy a MacBook air in store, I can get around $200 off (Best Buy) because of people eager for commission, and various sales going on. an obvious issue in this is I'd be stuck with 4GB of RAM. But do you think it'd be wise to go buy it now, or in the Christmas season? Lots of sales going on, but would there be any to use as a bargaining tool against stores? Or maybe I should just pay $300 more for my extra 4GB of RAM.
