<prompt> Human: just comming here to ask about the amazon credit card. hopefully someone here has onehas had one and can shine some light on them. seems like pretty high intrest, but i do a decent amount of amazon shopping and it could be a easy way to build credit on purchases that i already make, but i dont know much about credit cards.Assistant: If you get one, dont ever carry a balance. Pay it off full every month. That way the interest rate doesnt matter.Theres nothing wrong with the Amazon CC as long as having it doesnt hypnotize you into buying unnecessary things, or spending so much that you cant pay it off in full each month.Human: okay! will i still build credit paying it off in full every month or should i leave a very small balance on it?  <response>: Always pay it off. Theres a myth out there that says youll gain credit status by leaving a balance payable on CC accounts, month after month, but thats not true. You get the biggest boost by using the card only up to about 20 or 25 of your total available credit line; paying off your balance completely each month; never being late with a payment; and keeping the account open for the long term older active accounts higher credit score.
