I truly don't mean any disrespect, but why do you (general you) pay off the bill more often than once a month? I pay mine in full every month and never get hit with interest. Is it a discipline thing (i.e., that way you don't spend that money on other stuff)? Do you feel you get an added benefit from it? (For the PP who has to pay it off due to a low balance - that I get.)
If I had a balance on my CC that I couldn't pay that month, I can totally see making extra payments, because I'd want to accrue the least amount of interest as possible, but that'd probably be the ONLY reason I'd do that.
Again - no disrespect - just trying to understand...
