Well I put about 100k a year on my mastercard and I get 1% cash back on it. As I figure it, they're giving me a free tank of gas every month
My house doesn't offer any deals on cash as far as I know, nor do I wish to inquire of the dragon lady in A/R. I was finally able to get them to send my monthly statement and all my slips in the same envelope, rather than getting a slip mailed separately every time I bought a widget. Only took 2 years of asking...
