Well, this is what Mrs. Smug here does:
All my regular household bills are paid by Direct Debit and I use my Credit Card for almost everything else. On the first of each month, I deduct all the direct debit payments from my account even though they are taken out at different times, that way I know exactly how much 'disposable' I have.
When the credit card bill arrives I transfer the amount owing from my savings account to my current (checking) account and pay the full balance. That way I pay no interest and my bank statement is not cluttered up with loads of small payments. Also by working this way, if my Debit Card is stolen or cloned, there will not be too much to lose in that account: my Savings Account is not accessible either by card or cheque (check).
Of course there is always the chance of falling foul of the Credit Card fraudsters, but at least they can't get access to my money and the Credit Card Company would have to stand the loss, not me.
