Lazy people get what they deserve – nothing. If that moron was selling your product with your sales page, he (or she) can only expect to sell far fewer copies than you, the originator, because most people have already seen it and know what it is. If he’s jacked the price up he’ll be lucky to make even one sale. Equally, if he’s practically giving it away, then he’ll likely make very little from it, so he’s a loser either way.

I guess you can at least take comfort in the fact that you got his money first ;-) !!
