A loyalty program (savings program) is a publisher that promotes advertisers. They do this by giving affiliated members points for clicking on links. When members buy something through one of these links, they often get even more points. The points can later be redeemed for cash or gifts.
Loyalty programs are often very successful with Affiliate Marketing and can generate substantial numbers of additional sales. They often have tens of thousands of affiliate members, allowing them to send many visitors to an advertiser in a very short period of time. Often the promotion is done via e-mail.
