I used to use just my debit card, but since getting some credit cards with cash back or airline miles, we converted to using credit cards most of the time. Since I am not using the debit card, the money is in the bank, so I do not feel like I am borrowing money.
We always pay the entire balance each month. I usually pay any CC bill right after the statement is available to download online.
Sometimes, when I make a large purchase for something, I will pay the CC off a few days after making the purchase from our saving account. This would be for things like travel reservations, timeshare MF, annual homeowners insurance or estimated taxes. I have the money available and do not have a debit card for savings. It is easier than writing a check and mailing it.
It works for us.
