Hi my friends What I do is call referral marketing. In the bottom of the page there was an advertisement saying work at home united and they do the same too. What I do is that I explain to people where I buy my day to day shoping on-line and then I register them, if they want to. I help and support any one who wants to do the referral marketing. Lot of Americans are doing and it is growing very fast. It is an opportunity that is available who likes to do it.
