Free Happens Loyalty Game. 

Free to use users and merchants only pay when the app works for them the use cost is from .25 cents to $1.00 each time they make a sale. 

The loyalty cost is preset by the merchant by percentage of use. Example the merchant can set the percentage to 5% of sales the Free Happens generated, So if Free Happens helped generate $1,000 in sales the merchant cost will be $50. in product discount, plus the use cost. Use Cost is only calculated when a sale is made, no assumptions. If the average order is $50 @ $1 per use then the use cost is $20. for the sales the app generated. 

It is a game and people like to play.
