Culk review for Referral Candy & Affiliate

We've never done referrals and would like to see how we might be able to test out different programs. Derek on the customer support team was *ultra helpful* getting me up to speed on what our options are and how Referral Candy works as you adjust the program — e.g. what do past customers see when the referral program is changed from dollar to percentage discount? Can't wait to give it a shot and see what happens!
