Can't use a balance transfer because both cards are from the same company? Yes you can!

They won't tell you this but you can use a balance transfer from a low interest card to transfer the money into your bank account. It's really like a cash advance but they have to do it as a balance transfer if they offer it. Then you use that to pay off their high interest card anyway.

At least that used to work, unless they changed the rules. I did it once a few years back.
