I can't remember the last time I used cash. Probably when I bought something on Craiglist earlier this year. I don't even remember when. Before this, I only used it when I absolutely had to. I usually carry it though. I've had the same $100 bill for at least two months now. It and rest of my cash has been sitting in a drawer for the last 5 weeks. I don't even carry a wallet now. When I go out, I take one card, my car key and a pair of reading glasses. I have a cleaning station in the garage where I clean everything before briging it into the house. Haven't filled the car in over a month. I think there's still over 200 miles in the tank. I don't even know how much petrol is at the moment.
