Office I am demo'ing does 10% off all products if patient is on a membership. Would be easiest if products could be in a fee schedule, so they can set and precalculate the discount and then attach that fee schedule to anyone on the membership that qualifies for it.

Create a New Fee Schedule, you could populate all your current prices with one click and then adjust from there. Having a calculator at this level would be so much simpler to build as well. As an example, you Create New Fee Schedule, Copy all fees from your main price list, and then use calculator to adjust all or individual codes by $ or % off, update, save.
