Creating Appointment Packages?

Hey! I've been able to everything I've needed to so far with the Appointments+ Plugin -- Brilliant. However, now I am now trying something a little different... Appointment discounted packages...

My client wants to be able sell a, b, and c appointment packages. A = 1 appointment for $1, B = 3 appointments for $2.50, and C = 6 appointments for $4

Are there any workarounds to make this happen? Thanks!!
