A television service provider system includes interactive elements embedded within advertisements or other content related to a particular product or service that a user may select to receive an initially non-redeemable coupon for the product. The system then electronically communicates to the seller or advertiser system the indications of such electronic interactivity between the viewers of content and content related to the product being sold or advertised. The advertiser or seller may then electronically activate and thus convert the non-redeemable coupon into a redeemable coupon. A system for processing retail transactions redeems the coupons for the product for a particular user using an identifier of the user associated with the account of the user with the television service provider.
