Did you get $1.50 or $1.55 off a gallon? With a linked Shell Rewards card to the S&S, you should get another nickel.
I always do gas. When we had a string of weeks with "any gift card" getting points, I did run out of ability to store gas so started instead getting diesel and filling my home heating oil tank. Not much of a limit there with a 275 gallon tank. My Jeep has a trailer hitch rack and I can line up 4 or 5 gas cans, so getting 20 gallons (or back in the day, 35 gallons) is no big deal. I have noticed that all the Shell gift cards at S&S are only $25 now. Far better when they were $50 so could be spent filling $1.55 off gas. Anyone seeing $50 or $100 Shells at S&S? I'm almost tempted to grab some from the shell station and try to then "buy" them at S&S. Hmmmmm.
