I have a method, which is actually very very basic and well known, but it's got a bit of a twist to it. I guess you could classify it as arbitrage. You'll need to spend $20 up front, which you can get back, plus I will be paying $20 to do it. You'll see how this is repeatable when I tell you it. This works for the US and for Canadians only. Please PM me if you're interested.
