I will tell you how they benefit from it:

There are many gaming websites, gambling, etc... That offer points, coins, tokens, whatever it may be on that particular site, in exchange for signing up for things on the internet. So someone has a CC#, are not interested in the product itself, only the outcome of getting the credits on the website, you get the item, and get to pay for it, and they get the points. Fun huh.
