<prompt> Human: It was probably pretty silly of me, but I applied for Amazon Store Card to see what kind of limit I would get. On second thought, I realized I probably shouldnt have it. Im not sure my income will be correct because Im a self-employed balloon artist with no real job right now. Should I cancel, or just hold onto it? I only have 1 card right now Discover, and its my only credit. My FICO score according to Discover is 753. It just went down 82015 from 772 because my only line of credit is the 1 card.I applied because Im thinking about financing a laptop. I probably wouldnt spend more than 700 on the laptop, and am pretty sure I could pay it off within the promotional period 12 months. My income right now is variable- Im self-employed- but I dont have any other bills besides general spending. I pay off my discover balance every month, and stay below 30 of my limit. It wouldnt be too hard to monitor my spending and make sure Id have the 60 or so per month for the laptop. Would it be worth it to keep it, or should I cancel since Im not sure of my income?  <response>: Keep the card even if you dont get the laptop. The drop in your credit score from applying for the card wont go away if you cancel the card, but having 2 cards will raise your score faster than 1 card. In general you should not close a credit card account unless they charge fees to keep it open.If you are 100 sure you can pay off the computer before the 0 promo ends then get it. But if there is any chance you might not, then start saving and pay cash instead. If you do get it try to budget to pay it off a few months early, just in case something happens.
