It's your subtle editorializing that annoys me.
Interesting take. I use my credit card for all purchases. Why not? I pay the balance in full every month, and since it's a SW card, I get anywhere from 2-5 free flights a year as a result.
As such, though, I'm on my online portal every day tracking purchases, balances, etc. If fraud occurs, I'll catch it early, but given all the different vendors who will have obtained my info, it'd be nearly impossible for me to determine where said fraud originated.
