Best Buy's Black Friday sale in two weeks will be marked by key sales on Macs, e-readers and smartphones, a copy of the flyer shows. The big-box chain hopes to head off likely Apple sales by offering a $125 gift card for buying either a 13-inch MacBook Pro or a 21.5-inch iMac. The deal isn't the steepest for the computers Best Buy should have on November 26, as BFAds notes it will also take $150 off of any Samsung notebook and take $200 off of a Pentium dual-core equipped Sony VAIO EB to bring it down to $400.
