I can add one more "gotcha" to the list of delayed gratification discounts. My CVS "Extra Bucks" coupon was printed using a cash register thermal printer. It was a warm summer, and when I pulled out the coupon to use on my next trip to CVS, the print had virtually disappeared. The register clerk declined to accept it (I guess I can't blame her), so, miffed, I sent it to CVS (after getting no response to my first email). Sometime later CVS sent me a new coupon for the face amount--how generous--worth considerably less after my time and postage in lodging the complaint.
