<prompt> Human: Hi all, I have a credit card my parents opened for me when I started college. Its about 10 years old now I think. Over the past 2 years Ive opened 4 new cards. My credit score is around 720. Just recently, the bank for my first credit card sent me a letter saying my card will be deactivated if it remains inactive. I am wondering if I should let it deactivate, or if I should keep using it. The credit limit on that card is much lower than the credit limits on my new cards, and my new cards have much better rewards programs, so I dont really feel like using the old card to keep it active. Will closing that card hit my credit score too hard?edit: thanks for all the advice. I will use it to pay for Netflix and set it on autopay. Never thought to do that!  <response>: Keep it, youll be glad to have it around when you need your credit score. Just put your netflix account on it or something. The difference of 3 cash back would be 30 cents a month.
