Even if they raise the price to $58 (before promo). If the trade in price to Best Buy holds until tomorrow its an excellent way to transfer credit to Best Buy. (and make a little side profit)
Yeah, either way you'll make a minimum of $11 profit ($29 GS to $40.50 at BB - and this is assuming it sells for $58. If the price holds at it's current value, you'll double up at BB.
