> regularly maxes out his credit card so he can pay it all down and rake in the score bump Does it really? I have a very high credit score but putting a large charge on one credit card (nowhere close to maxing it out though) dramatically drops my credit score for one month until I pay it off in full at the end of the month. I pay my child's tuition in full for the year each August (school in California is way too expensive so it's a lot of money, but that's a different topic). I put it on the credit card to get some cash back. My credit score drops by about 150 points right away. Once I get the bill at the end of the cycle and pay it off, the credit score goes right back to where it was before. I don't get any bump though.
