Just ordered a new iMac from MacMall. After receiving the order, a woman called me regarding a "security problem" with my AmEx. Even though they are shipping the computer to the same address as the billing address, she asked me a series of ridiculous questions, some of which were completely unrelated to the "verification" process. After verifying my identity, my 3 previous address (dating back 10 years), and the credit card, I told her that I was not going to continue with this nonsense and they could either ship the computer or cancel the order. She then asked me to contact AmEx and have them add my cell phone # to my account (since that was the number I was calling from). I told her absolutely not and to cancel the order. She quickly agreed to just ship the computer. On top of this hassle, MacMall doesn't accept ANY returns on Apple products, even though they claim to be the #1 reseller. Take your business elsewhere.
