I've got a better idea, Dion. You send the universal converter to me FIRST, then I'll pay for it . . . this is the proper way to do business with "NGF". "NGF" sends the product, then waits for the customer to pay for it, when the product actually arrives and they're satisfied that works and is acceptable.
And even better, you should have the customer pay what they FEEL it is worth . . . sounds fair, doesn't it?
