Best Buy, Macmall Start Mac Discounts For Black Friday Now: Up to $250 OffSFry's MacBook deal may have turned out to be too good to be true, but these sales prices are real: Best Buy and Macmall are offering up to $250 off Macs. The full list is here, helpfully compiled by MacRumors, with that $250 being on 15- and 17-inch MacBook Pros at Macmall with on-sale discount and mail-in rebate. iMacs, regular MacBooks and Airs get around $100 to $150 off at both Best Buy and Macmall. We'll just have to see how Apple's own crazy discounting matches up to this on Friday. [MacRumors]
