Caribou Coffee advertises in the drive-thru to register your gift card and get $4 added on! What they fail to tell you is if at any time prior you have ever registered a card online at their web site, you do not qualify. How can they do this and not post this with the information with their promotional material in the drive-thru. I feel like it's false advertising. I went back and forth with customer service via email on trying to understand this - and with the last email she even called me by the wrong name. I'm not impressed at all.
