You don't have to enroll. The way their programs work is if you donate a certain amount of times a month you receive a bonus after a certain amount of donations it changes month to month but usually upon your 6th 7th and 8th donation of the month you receive bonuses on top of your regular amount. And sometimes they are run a gift card giveaway if you donate a maximum of x amount a month
