Do you find useful to have a referral program working with other stores?

Last time I saw that my friend's household store cooperated with another food shop. If someone spent over $50 in the food shop, he could get $5 redeem if he spent over $100 in my friend's store. 

I am thinking if this model can work for online store. As a store owner, are you interested in such referral program?
