I would not open a bunch of store cards.
Look at prequals for Cap One and Discover.
Honestly I'd hold off on any new accounts. Let them age some. Reason why is..."I got a self lender, discover, and Fingerhut right after. I recently got an Ollo cc and an auto loan." Thats 5 accounts since Feb and should do for a while. If recently was in the past couple months or less. Wait at least 6 months before any more moves. You have plenty for now. Since you have a car loan now. The self lender will help with payment history and thats about it. FICO rebuild stages you only need 1 installment loan. Now the auto loan is your main loan for the next how many months you got it for. Each new account hits your reports and drops your scores a bit. It takes time to get back that was taken away from you each time a new account is opened. Let these age and let time do its thing. JMO I'd wait until next year for that store card and let your rebuild work in your favor. Good Luck!
You dont have to kep buying overpriced stuff to keep Fingerhut open. Let you in on a little secret. In the past over 4 yrs since my DC I havent paid 1 red cent in interest. If you see something you like that would cause you to pay interest. Throw the $ in a savings account. Once you hit what you need to get what you wanted. Then charge it knowing you got the funds to pay for it. You get cash back. And as I say on here. You make a profit from the cash back. You dont lose your profit paying interest. Let the banks pay you for using their card. Dont pay them for using the card. Why have a cash back card and what you earn goes back to pay interest? Make sense? Profit gone. Fingerhut can be closed since you got Disco and Ollo. It will still report as a positive account for the next 10yrs. Then say happy new year. And get the store card that you'll get rewarded for using. Good Luck!
You can just keep Fingerhut open and buy some socks every 4 months or something. That should be enough. You have a Discover It and a Ollo card—they can be used anywhere.
I hesitate to recommend this because I don't think you need to get it, but an Overstock card would be better than Fingerhut. Overstock was my first unsecured card after my credit meltdown. (Which was bad, but not bankruptcy.) I bought the aforementioned socks through Overstock for a good price. To keep the card active I use it once in a while on some small thing that I actually can use and isn't overpriced. Not everything at Overstock is to my liking, but it's no Fingerhut, that's for sure. Overstock (from Comenity bank) also can be generous with CLIs. Not sure how Comenity feels about bankruptcy, though. I don't think they're picky, however—they took me!
