We have a Safeway about 15 min. away. They did a remodel last year. It was only two yrs old, I think.
Anyway, I have used the rewards card for gas. It wasn't the best gas for the vehicle I was driving at the time. I used lot's of gas additive. Also, it wasn't the best priced even after the discount. People are using it though. If it works for them, go for it.
