In trying to purchase a radio online, Bestbuy.com site refused to take my rewardzone certificate. After 60 minutes of being given the run around by customer service on the phone, I was told the certificate could only be used toward half the cost of the item. This is unbelievable and a clear con. The certificate clearly states they should take the full cert value toward the cost of the radio. I suspect they are deliberately trying to stop customers redeeming coupons by lying and or finding other ways to make redemption difficult. Best Buy is completely immoral and I recommend you find another retailer. Come back Circuit City! read full review »
