If I am running a website and have displayed online coupons of certain businesses, how do I get paid by the businesses? I don’t have access to their records so how do I know that a customer came to them through my site?
An example would be:
Let’s say I have a coupon for a local grocery shop. A customer comes to my website and prints that coupon and takes it to the local grocery shop. How do I know that the customer redeemed that coupon with the grocer?
