i haven't read something that I think is a good point to make, never charge more then you have the cash to cover, then paying it off isn't a problem. as I mentioned before I have always payed my cards off every month
and yes I do realize that sometimes you have to charge more then you have because [censored] happens, like it was said just make sure you can handle it, and not paying a card off every month is ok from time to time, just can't let it get away from you
