Just bought more today and it rang up no problem. As PP's have said we usually know more then they do. I think what happens is that you can't get the discount on Target GC's and cashiers tend to think that means all GC's. I think when most people pick up a GC, for Disney, Chilis, or whatever they are only picking up one maybe two and most likely with a couple other items so when the 5% comes off the cashier doesn't notice that the discount works on the cards. I have had a couple cashiers look surprised, probably because I tend to buy 20 or so a time, and when I told them about the discount they said they would def pick up the GC's when they go. They were also surprised when I told them their employee discount would work too.
