We have a couple of bills

who doesn't right lol
Any way I am torn as to which one to pay.
With the little money that we got from the house I can either pay of dhs car low interest rate (250 monthly) a bill that is interest free (480 monthly) or a credit card (highest interest even though they are extremely low for CCs).
Which would you pay and why?
I really want to pay off the 480 one but it sucks that it is intereste free. If I pay off the CC I am afraid we will just rack it up again (can't cut it up cause with the pay getting screwed up every payday and dh leaving shortly with no idea as to when he will be back gotta have a back up). I hate dhs car and would like to pay it off too but the interest is so low it may not be worth it, except I wouldn't have to write a check every month lol.
So what would you do? I need to do it before we spend it on something we really shouldn't lol.
