how do credit cards work?

[t-maxxracer32]

ya thats one thing i didnt understand.

for me i would not be stupid with it 100%. i do not NEED anything so its not like i HAVE to charge things.

i always have money in the bank anyways so the CC would be only for building credit.

i think if i do get one my first purchase would be an erevo.

in 1 month i can easily get enough money for it.

but why not get it now if it will help build credit.

i may buy 1 big thing a month with it. then gas and other things like you said.
