Always: Refer a Friend Discount. When you refer a friend and that friend books with me, you and your friend will receive 20% your next sessions!
Currently: When you book a two-part senior session, you will receive 27% off your session.
A two-part senior session is a premium session of one hour or more of shooting time. This deal would work best for those seniors that just do it all. I would have them split for half the time to shoot casual photos, and the other half to shoot sports/extracurriculars/high school achievements.
