Yesterday i went to bestbuy to buy a 2014 base 13" mba. They matched b&h and amazons low price of $819, but refused to also deduct another 10 percent with the usps movers coupon that i have. I thought that was bs on their part but they claimed for an apple product only one discount, but not two. Any ideas on how to get the additional 10 percent? I thought maybe taking the receipt in with the coupon and asking for the additiinal discount at another bb. Any Ideas.
