<prompt> Human: So the backstory:My family and I are headed to Montana for a week for summer vacation and needed some good riding boots in order to go horseback riding. We went to a local Boot Barn and got boots for the whole family and a couple of pairs of jeans as well. It was a pretty expensive purchase boots are certainly not cheap and at the checkout the cashier said we would save 20 if we applied for a credit card. I usually immediately turn away from gimmicks like that, especially at a place like a Boot Barn, but my dad asked if I would do it to get the discount. I was very hesitant but agreed, not wanting to be put in an awkward position or cost my dad more money than he was already spending on me. I am 20 years old and currently have one credit card for a total of 7 months. I have never missed a payment, always pay the full amount, and am very much on top of trying to put in the work now so that my future self wont have to worry as much. My credit is something I really want to keep pristine and I am wondering if opening another line of credit this soon after opening my first line will hurt my score. I had considered opening another line, I currently have a Discover IT card and was looking into a Chase Sapphire, but certainly didnt think Boot Barn of all places would be my next choice. Im really not to keen on keeping the Boot Barn card, Ill probably never go back to Boot Barn after this so Id rather reap the rewards of another credit company, so would it be wise to cancel the card or just hold on to it? Thanks in advance for any help!  <response>: Cancelling the card will not erase the effect it has already had on your credit. You got the hard pull, and your average age of accounts decreased. However, you now have another account to contribute to your credit history, so it will end up helping you in the long run. If it doesnt cost you anything, then jut make sure its paid off and leave it alone. If you happen to go to Boot Barn again, use the card, but if not then it will eventually close for inactivity, but it will at least be contributing to your credit for longer.
