Typically the rule is: no AF, keep open.
If you regularly shop at the store, I would keep open.
However, if your ONLY shopping at the store to keep the card active (buying things you normally would not buy), I would close it.
How are you on HPs? I would say - hear me out - close ALL those retail cards except Sam's and ask for a CLI on the CU card. Yes, I did read the details on all of them, and none of them are offering you much value. Keep CU visa and Sam's as well as Navy, obvs. You will also still have the others in your sig on your side, e.g. Discover, Cap1, Amazon so it's not like you'd be dropping below 5 or 3.
If you're nervous, you can go in tiers. Start with Overstock, Ulta, Fullbeauty.
Full disclosure: I like to keep my wallet on the thinner side, so that's my bias. If you prefer to keep around a retail card or two, it's totally your decision, but since you asked for advice, that's mine
A number of people on these forums knock the Comenity SCT cards. When I was in my rebuilding stage I applied for several of the cards. Overstock started me off at $10K (now $10.8K). Sportsmans Visa was $9K (now $13.5K). Fuel Rewards MC was $6K (now $9K. Yes, I know it will soon close). The total CL for my six Comenity CC's are $42.3K. That is out of my total CL of $156.5K. FWIW: The A&F CC was to show loyalty to my daughter who was working at its HQ at the time. Having these "Toy Cards" doesn't appear to have hurt my getting approval for Discover It (now at $22.1K), AmEx (now $22.5K), Citi (now $12.4K), US Bank (now $6K), Citi AA ($6K), Barclay ($5K), and last week Chase ($15.7K, and I had burned them several years ago and I was at 5/24). Throw in a Visa and a MC from Cap1 (both stuck at $2.5K) and a few other store cards which offer me excellent discounts or dollars off when I signed up (Who is going to turn down $75.00 at Home Depot for getting approved?) I have turned down pre-approval for a several AmEx CC's (too cheap to pay AF), Citi (not paying an AF), 5/3, Key Bank, PNC, and Marvel MC. I didn't see anything being offered that I thought was worth anything. My utilization is below 3% (Mostly on one 0% APR until next year CC). Scores upper 700's to over 800 depending on the source. HH's= 7, TU:3, EXP:3 and Equ:2. No mortgage, one new car loan that I pay $5.00 a month (owe approx $100) on to keep it open and not pay much in interest (from the original $13K financed )Gardening until two HH's are removed in August. With all of my CC's reporting on time payments for the past two and a half years my score has risen over 150 points (between 260 to 300 points increase since 12/13). I say, Thank you Comenity!
