You also fill up your vehicle with gas once a week. Currently you also spend $80 to fill yours up completely to the brim.
So we both drive all week and do what we normally do. However, you went to a web overview and learned about a program where you get every day fill up rewards. This program will earn you cheaper and free gas as well as other discounts on things you use regularly when you spend a certain dollar amount each month on gas. The cost to join was less than a wholesale club membership so you decided to take part in it, thinking that since you will use it so much it will be worth it. I wasn’t aware the program existed so I of course wasn’t able to take part.
