Businesses of any size can invite their existing clientele and receive cashback from all their purchases within the network. Let's say you own italian restaurant, sign up with us and start offering 10% discount to members of World Winners Network, so far so good. But what if you put flyers on the tables inviting your customers to create free account, start using discounts at your restaurant and many other places and receive additional cashback + money for donations? Next time these guys go for dinner across the street where the steak house is also our partner and you get portion of the their bill...same happens when they go to the gas station, grocery store or the gym to use discounts.
I believe the above answers both your questions and if not please ask anything you would like to know.
