<prompt> Human: Im sure this is one of those if it was that easy everyone would be doing it type things, but after I was approved for a 10,000 credit card, didnt seem much of a stretch to get 4-5 more and place 50,000 into savings accounts, have interest paid on the accounts and then pay back the credit card company in time not to have any card interest penalties. My undoing was that the interest free period only relates to credit card purchases -any cash withdrawal would be subject to normal interest immediately. Any one tried this or found a way?  <response>: Cash advances have no interest free period. They start changing interest as soon as you get the cash and they usually have a fee as well.
