I received a coupon last week for a free CVS item on the bottom of my receipt. It was lens cloths valued at $3.49. Our CVS is smaller and doesn't carry them. This is the 3rd or 4th time this has happened to me. This time, I mentioned it to the cashier who promptly offered to take $3.49 off my bill!!!! SOOOO, I was able to apply the coupon to other items I was purchasing! Pretty cool huh?
