Free Bacon- Paid No Tax!

This week Harris Teeter had Oscar Mayer 12oz turkey bacon on sale for .99. I had a .75 coupon from a few weeks ago off any oscar mayer bacon. I used the coupon and the computer tried to double it, but it was more than the bacon cost so they just subtracted the $1.01 I owed off the coupon! Nothing like free, not even paying tax! I was prepared to pay it but wasn't going to argue with them :)
