This is tempting, but you should hold off: MacMall and Best Buy are in a discount showdown over the price of new Macs, with no clear winner... unless you're looking to buy a MacBook Pro, as I am, in which case, MacMall is blowing Best Buy... [Tobias Funke pause].... away.
Except they kind of aren't: MacMall's prices are based on instant discounts and mail-in rebates. Even in the best of climates, there'd be little chance of you getting that rebate — rebate houses love to dismiss your claims for the most frivolous of technicalities — but given the recent bankrupting of major rebate houses, there's less reason to trust them than ever.
Either way, you should hold off: Apple's web site is teasing their own Black Friday sale, and they have recently promised to match all competitors prices. So worst case scenario is that on Friday you'll get the same discount anyway, and best case is they'll actually beat it.
