I know that  Eeekay did a "patreon credit" (discount) for patreon members.
At certain tiers, some of that pledge could be used towards a regular commission, plus a slight % discount.

Looks like an interesting idea in theory (especially if a patreon exclusive pic/situation isn't what the member actually wants for that particular month).
Something to consider!

Oh yeah, I love that idea! I've actually been considering that but wasn't quite sure how interested people might be! I'll deff take a look at Eekay's for advice.

I'm also thinking of offering 50% off new Commission types for when I need examples for them, as a tier reward.
