I'm building my daughter a Disney Movie collection I went by my local best buy today 1/8/12 to purchase Lady & the Tramp blu ray Disney Movie Rewards gave me a $8.00 off coupon I also had 40 dollars in reward certificates so I picked up 2 other movies and a Final Fantasy game for my Husband. I get to the line, got rung up handed over my coupon and certificates and was told I could not use them both at the same time. I asked why not and was told its Best Buy Policy. I do not think of my certificates as coupons those are money that I already spent my percentage back. I was not aware that I could not use Mf coupons and certificates together and just want to know if this true
