Okay folks...so I'm following the "Exclusive MacRumors Discount: Additional 3% off iMacs in addition to existing rebates." link from the MacRumors main page which takes me to MacMall. I add the 27" iMac i7 to my cart and proceed to checkout. The additional 3% discount is not showing up. All I get is the normal mail-in rebate line item. Can someone enlighten me? Thanks!!
