I've paid off and closed another account. Hooray for me! As usual with "payoff quotes", the balance they quoted was not quite accurate. Usually in these cases, it's the customer who ends up owing the creditor a couple of dollars to make up for interest somewhere. In this case, I received a refund check for... eight cents.
It cost them $.37 to mail the envelope, probably a penny or two for processing, and two minutes of call center rep time when I called to confirm that the account was really paid off and they owed me eight cents.
I wonder what my bank will say when they receive a deposit of eight cents?
