Socratt, I have heard that some banks will soon be increasing minimum monthly credit card payments so they are closer to 4% rather than the current average of around 2%. Some major banks have already increased the minimum payments and others are about to follow suit.
I heard a caller on a talk show last night say that Chase just did this to him on one of their low interest loans and that he might not be able to pay it. Then the rate goes up. I am sure you are not in the same boat, but it is something to be prepared for.
