That one wasn’t card. I got a haircut and it came to $55.95 but I only had $55 cash so the guy said to just give him $50. That works out to more than a 10% saving for going cash

Haircuts and every food place that has a surcharge for card

I can save 1-10% on some things by using cash. Do that over a year and it all adds up. Isn’t that the sort of financial advice some motivational speaker would give you?
