FWIW I just sat at budget.com and plugged in at least 10 coupon codes (their site makes it fast and easy to do so)... none of the coupons affected the price EXCEPT the USAA code, Y126501.

I'm checking rates at a suburbs location in Kansas City (610 W 103rd St) for a weekend rental, FYI.

Incidentally, I am actually a USAA member and don't have a membership card to show for it. If they give me any hassle at the counter, I'll ask them to call USAA and they'll verify my membership over the phone.

Good luck...
