I use cash because you know what you have at all times. With the farm, we used to be pretty much hand to mouth, and every penny spent on family living couldn't be used on the farm. It is a great way to keep on the budget. When the cash is gone, you are done for the month. Old habits die hard. I still do it that way.

If you go inside and pay, the pump will automatically stop when it reaches the dollar amount. My TSC card will only allow me to put 30 gallons in at a time for some reason. When it gets past 29 1/2 gallons it really slows down to a crawl. You can watch the pennies go by. I question how accurate it is as gas pumps don't measure correctly at low rates. At least they didn't in the past. Better to eyeball it and be quick on the trigger. 😊
