Just occurred to me that this promo's great for business renters, as it's a way for the business traveler to get something back, whereas with a standard discount, the employer saves the buck.

Do you remember where the gift card was mailed from? I've been told that the promo's dependent on Amex, and if there are any delays or problems, that people should call Amex to complain or ask (not Thrifty). Did Amex mail the gift card or was the return address Thrifty?

Also, curious about your experiences with Blue Chip. I have limited experience with other companies' programs, but I haven't found noticeably better experience with, say, my Emerald Club membership. If all goes well with Blue Chip, it's pretty quick and painless--the worst I've had is that it wasn't preprinted and the rental took a couple minutes instead of the under 60 seconds that's guaranteed. (Since I usually like to chat with the rental agents, I don't stick them with the free day guarantee for my rental not being ready...)
