I was using my Discover IT for gas but I think I might start using my Freedom for gas this last month.
At this moment i use the Discover IT for Gas only, Amex BCE for groceries only, and the CSP for my traveling and dining and everything else that isnt gas or groceries.
In my wallet at the moment are:
1. Citi Forward Visa Signature (use for 5% restaraunts, movies)
2. SPG Amex (use for all other types of purchases - 1% points)
3. Priceline Visa (use for all other types of purchases where Amex is not accepted - 2% points)
I rotate the others in for low APR, 5% rotating categories and/or other spend promotions.
Chase Freedom-5% Category Spend (gas at the moment)
AMEX Green & BoA Cash Rewards go pretty much unused. Just got the SPG, need to get going on that minimum spend.
Currently in my wallet:
Student Discover It & BankAmericard Platinum Visa
Patiently waiting for arrival! American Express BCE
I mainly used the BOA and CSP for daily purchases. I'll get around to getting a freedom card and a SPG, maybe January. I need to do some pruning or gardening, my goal is not to be stuck with any low limit cards under 10k cl.
BCP/Costo---Groceries and Costco
BofA CR- Gas (and some groceries)
United-Travel Tix and Bills
Citi TYP-Clothing and everyday spend
CitiAA-Travel and Bills
Barclays-clothing and Gas
I have stopped using and SD the following cards ( Cap1,Discover, US Bank, Citi Simplicity, Walmart, Dillards, Macys, Amex Green) The Macys and Dillards will use come November/December.
Discover - 5% rotating cashback
BofA 3-2-1 - 2% for groceries
Target Store Card - 5% cashback at Target
B&N Mastercard - 5% cashback for B&N purchases (nice since e-books don't typically get discounts otherwise)
Delta Skymiles Amex - 2x miles accrual for flights
Paypal Business Debit Mastercard - 1.5% cashback (catch-all card, though technically a debit not credit card)
At the moment my rotation looks like this:
Discover It or Freedom- gas
Chase Sapphire- dining
Capital 1 Quicksilver for everything else
