All of my friends do that, as do I. Hell I wish I could pay my mortgage with a CC laughing1 Depends on how you are with money. If you treat it like a debit card and never put more on it than is in your account (watch your cc balance vs your bank balance and keep it right) then you will never have a problem. CC companies aren't huge because people pay in full every month, they are huge because you just go over $50, and then that much the next month, etc, now you have a snowball. If you can pay all your bills then pay in full every month there is not one single reason not to. If you live paycheck to paycheck and there is a chance you might be short, you have to use caution and really trust your wife laughing1
