Gas...Canadian Tire? Petro Canada? Shell?
I was just wondering where you all gas up and why? I used to go to Petro Canada for many years (using the Petro points card) but, since we've moved a few years ago, my son asks me to gas up at Shell for the Air Miles rewards. Now I'm thinking Canadian Tire might be more worth it for the CT dollars since there's always a coupon in the flyer for a minimum of 7x CT dollars. I fill up for approx. 100$ per week. Would CT be my best bet? Has anyone done the math to see which program is most rewarding?
