We have an all electric home and it is paid with the card. Groceries go on the card because groceries for the two of us now cost over 3x more than our electric bill. Funny, I remember when groceries were way less than electricity for this home. Not funny because I'm pretty sure that will be true again.I have all our monthly bills - internet, phone, water, electricity - charged to a major cash-back credit card every month. Every day purchases such as gas, groceries, spark plugs, etc, just get charged to the bank card. Except those purchases that can be paid for with a $20 bill, as I mentioned.
