OK, OK, OK, I'm guilty also. I use my Credit card for all my Gas purchases but I always buy my gas at the same gas station so nobody can tell where I've been. With that said, I do sometimes use the Interstate highway to go to town and they have those High Resolution Cameras mounted here and there. If they really wanted to, they could read my License plate. Anything I buy from Amazon goes on my card and once or twice a year I might buy some groceries with my card. There was a time, way in the past, when I first started prepping, and I used my card for new guns and ammo. Today, I would never do that.
