I wouldn't endorse a product unless i use it or plan on using it. IDK why but I dont think I could endorse something knowing it isn't a great product and that I would personally never use it.
Those of you that say money talks, don't forget that the companies that you do use have money too!lol I'm sure propositions would come from everywhere, just choose the ones you believe in. No one would ever pony up $100,000 bucks

. A few thousand and free products is enough for me, should be for anyone else.
I say show me the WR buck, then I'll worry about the money side of things.
