Thanks for the link!
I used mine today, but they had to call a manager over because the candy is on sale, so the register didn't recognize the coupon. Then they told me I couldn't use it because it had to be a $2.79 bag of candy, which they don't have because it is all on sale. Then they told me I didn't choose Halloween candy, even though I had the same kind and size specifically written on the coupon and I got it from the HUGE stack of Halloween candy displayed right when you walk in to the store. The poor cashier was so confused they finally had to void my whole transaction (somehow my total ended up higher than it was before I gave her the coupon) and start over, and the manager told her to just give me the bag of candy and not ring it up, but at least I got my candy! It does pay to politely press the issue when you know you are right.
