My Personal input is, as long as those other two cards have no membership fees, dont close them. If you have the self control not to use them, keep them open and thats it. maybe buy gas a few times on them and pay it right off.
Im going back down from 12 to 4. I decided it was pretty ridiculous to have all those cards for no reason and it wasnt helping so im closing them all. Im just going to keep one of each. Discover, AMEX, Visa and Mastercard, then I have my debit card, which is pretty much all I use.
Oh and on the 25% one, do you have enough to balance transfer to the other one? id definitely get rid of that unless you can sacrifice and pay it all off in like 1.5 months. If you dont, and you get approved to balance transfer to the new CITI card, I would, but not use the CITI card til the balance transfer was paid off.
