<prompt> Human: I just graduated with my BS and will continue to pursue an MS this fall. Ive had my current credit card all four years of undergrad and never missed any payments, often paying the balance off when it got close to my limit regardless of the due date. I have a discover card and Ive had multiple occasions in the last couple years when discover was not accepted. So in order to not keep relying on a parent to pay for something I am unable to Im thinking it would be a good idea to get another card. I would just take something I already usually buypay for like gas and just use that card for that plus those situations discover isnt an accepted payment. Thanks for your input.  <response>: Absolutely. It sounds like you are very responsible in regards to paying off your card, so theres no harm in getting a second one. Your credit score will take a small hit from the credit check and the decrease in your average age of account, but thats no reason not to get a second card. Your credit score will recover quickly.If its primarily gas stations that wont take your Discover card, you might want to look into cards that give a good cash back on gas Go for something with no annual fee.
