I would expect many of us give a existing customer a discount for a successful referral. Many times its based on the amount of the new sale. For me it's usually a $15-30 one time discount. Others may do a percentage. I was thinking instead of a discount maybe I could go to some locally owned stores or restaurants and get gift certificates(for me a local steak restaurant and a "girly" gift store). Maybe they would sell me 10 $20 gift certificates for 175-180?? Then I could let customers choose. What do you think? What customer referral ads or programs have worked for you?
