There are some things I want to use cash for. I want to use cash to buy a Pepsi from the gas station. I want to use cash to buy a cheesesteak from the food truck out front of the courthouse. Mainly, I want to use cash to buy ammo and accessories from my local gun shop. Why? First, he does a 5% discount for cash (since he doesn't have to pay the card fee). And, it's none of my bank's business if I spend money at the gun store, and how much ammo I bought.
