A system facilitates provision of a first advertisement, including a first modular coupon, via a first network to a user, where the first advertisement provides a link to a second advertisement. The system further facilitates provision of the second advertisement, including a second modular coupon, via a second network to the user, where the second network is different than the first network. The system also receives the first and second modular coupons from the user and permits a discount associated with the user's purchase of a product or service based on receipt of the first and second modular coupons.
