On the last day of last month, I was in line a Kroger. The guy in front of me in line was checking out and the clerk said "you get 50 cents off your next fill up" he turned to me and said, "this is amazing. You get money off your gas by shopping her. Though I have had to spend a good bit to get my 50 cents off."
I didn't have the heart to tell him I had 6,400 points.
