<prompt> Human: Me: 26 years old, single, no car, 744 TransUnion, CapOne Quicksilver with 10k CL and Citi Forward with 2.6k CL. Do not carry balances.I finally decided to pick up a grocery card, seeing as how groceries are my biggest expense after rent and student loan payments. Everywhere I looked, people were recommending Amex Blue Cash Preferred 6 back on groceries or Everyday 3 back on groceries. Since I usually spend under 250mo for groceries, I decided the 75 fee for Preferred wasnt worth it and went for the Everyday. I was approved instantly, though I wasnt informed of my CL. I also decided to pick up a Chase Freedom card while I was at it to take advantage of the 5 categories. I was approved with a 8k CL.About an hour after my approval, I came across a blog comment about the SallieMae World Mastercard which gives 5 cash back on groceries up to 250mo. This, combined with its 5 back on books ahem...Amazon makes it a much better deal for me. I applied and was approved with a 7.5k CL. So, is there any benefit to keeping the Amex, or should I cancel after it arrives? Since Ill be using the SallieMae for groceries and will hardly ever go over 250, I wont be using the Amex much and it wont really be adding any value to my credit portfolio. If I keep it, Ill push 1k through it the first three months to get the 50 signing bonus, but it wont be doing much after that. I suppose my utilization will be slightly lower, but Im not a big spender and always pay off my cards every month, never going over 5 utilization even with my current 12.6k of credit. Is it worth keeping around just to start a good relationship with Amex in the event I want a better card from them in the future? Is there any downside to keeping it?tl;dr - Wanted a good cash-back grocery card. Approved for Amex Blue Cash Everyday 3 back, but found and got approved for SallieMae World Mastercard 5 back on groceries after. Keep or cancel the Amex?  <response>: Is there any downside to keeping it?Not really. No annual fee and you already have it. I would just leave it open.
