Credit cards used correctly are brilliant.

Where the banks have you, and they rely on it, is if you miss payments or go over your terms in the sense of the 0% APR.

I've had one a while. When I initially got it I used it to build credit and paid it off in full every month so paid absolutely zilch, O, for doing so.

When I bought my car I had the option to pay for it in full or put it on a credit card and pay a very small amount for an expensive product.
