We sell “access” to valuable coupons. Professional and businesses list discount they provide and we sell the privilege information to the end users.
The discounts are tied to the slow-hours of the provider i.e. get 20% off between 4-6pm when a lawyer is done with his/her regular court duties and has slow-hours. Or get 30% off between 1-3pm from a lawyer located outside downtown and is busy mostly in the late afternoons.
