PTF.
We're likely to need a new car in 2-4 years, so I'm not thrilled with the idea of cancelling any of our credit cards in the near future, as we may need a credit pull, but we have some legacy cards from 15+ years ago when we started building credit and didn't know any better that I'd like to eventually cancel and optimize. (Do I have a Barnes & Noble Mastercard from when I was 18 and thought book money was the epitome of cash back? Yes. Yes I do.)
I'm SUPER-intrigued by the Citi Custom Cash - I'll have to look into our utilities and see if there's an option and/or fee for CC payments!
Why cancel the old cards? They give you an overall increased credit limit, which improves your utilization percentage. They also improve your average credit age. I have a couple useless cards -- old Payal & Credit Union cards with horrible rewards -- I am keeping primarily because they are they oldest cards I have improving credit age, and also one of them has a $12k credit limit, currently my second highest credit limit of all the cards I have.
Yeah I love the Citi Custom Cash and U.S. Bank cards. I think those two are the best 5% cards.
EDIT: I tried ranking them last night according to how much value the cards give me -- or will give me once I get them all -- with respect to cashback:
1. Citi Custom Cash -- 5% groceries
2. US Bank Cash+ -- 5% utilities, 5% Electronics Stores
3. Discover It Cashback -- 5% rotating (10% the first year)
4. Chase Freedom Flex -- 5% rotating
5. Kroger Rewards World Elite -- 5% mobile wallet [drugstores, eBay, fast food, etc. ($3k annual limit)]
6. Citi Shop Your Way -- 5% gas & monthly stacking promotions
7. Chase Ink Business Cash -- 5% office supply (gift cards), internet, phone & cable
8. Chase Amazon Prime -- 5% w/ prime membership, 3% otherwise -- it's last due to the "annual fee" (membership)
Of the above 8, I am missing the Chase Freedom Flex, Kroger and Citi Shop Your Way cards. In the meantime I am using my recently acquired Amex Business Gold card for 4x on Dining & Gas -- I won't have this card for more than 12 months though as the annual fee is insane.
Of the above 8 cards, the Chase Ink Business Cash seems to be the most enticing at $900 sign up bonus and gives you 5% back on your internet & phone .. also cable if you have (we don't). Also 5% back at office supply for gift cards. [My business is a small sole proprietorship where I use my SSN on the Chase app. I get a small amount of income from referral bonuses, currently at around $300 hundred dollars so far this year.. but a valid business anyways.]
