I was doing research on the sites which are mainly based on Employee Discounts Program (I know a few sites but not sure if I should post their names here). Does anyone know how the business model works for such sites? The basic thing is that the site provides discounted services/products to the employees of the member company. The only requirement is that the member company must have a minimum employee strength of some X no. of employees (the site I was looking at has requirement of minimum 35 employees). The question is how do they make money and track the sales made thru them?
