my husband tried that, and it was a huge scam. If you look it up on wikipedia, it will give you some pointers of how to tell if it's a scam.
If they charge you money for a store list, it's a scam. That's what happened to my husband. We paid the "start up" fee, then they started charging all these fees to his Credit card. Not cool. We had to cancel the card to get it to stop.
He went and did a few assignments, but when he went to do the questionairre, the websites provided were no good too.
Same thing happened to my sister.
