Have you ever had a $50 or $25 coupon crawl out of the return clerk's hand-held device? I received this coupon printout (at the bottom of my completed-rental receipt) twice in the last year, when returning at the same local NY location.

Problem then was: on my next rental, both the return counter, and the pick-up counter before them, would refuse to accept it. They kept telling me that because I use corp AWD, I can't stack this discount...Finally, while picking up at an airport, I stopped at the counter and an employee did apply it (reads Adjustment +Coupon).

Now I'm more interested in procuring more coupons. Where/when/how?
