Merchants are the parties providing the products or services
Does this mean like for movies, free movie premiere tickets? or free hotel stay? or free gourmet experience? Who wouldn't want to be a helper?
There are no freebies! to be a helper will be undergone in so much trouble, you need to have a good background first with reviews online.
to be this on the team is not a freeman, you need to prove yourself to be worth one of them.
