Apple's got the cheapest price I see but that's not out-the-door. Compare Apple's price with tax to B&H or one of the others that don't charge tax and most can save around $100.
Best Buy and Amazon US are periodically offering the base 13" MBA for $999. If you can wait for one of these weekend events, you might save $200 or so.
thank guys! I think I will pull the trigger tonight. I guess $100 more or less won't make a big difference, I just thought maybe I could get a better deal...
