I pay off ALL my credit card balances monthly. I actually had a problem with a new debit/cr card when my bank changed over to a new bank ownership. I pay all my bills online & couldn't get the dr/cr card to work so I had to give my cr card I use for monthly expenses (food, gas, misc needs). Screwed me up but it still gets paid monthly.

Sometimes some companies will pass on the Cr Card expense they pay the CC company which does make things cost more even if you pay it off monthly avoiding intetest charges
