It must be nice to use your credit card to buy anything you forgot...Let's see..A computer, an I-Pad, Cell Phone, new suit, underwear, watch..,.wow that plastic does work..why didn't I think of that!!!
I use my 'plastic' for everything. If I have $250 cash in my pocket at any point in time, I'll most likely have $225 left six or seven months later. I get every 'point' I can during the course of a year and those little plastic things make it all happen!
