If you want to upgrade any previous commission to the next level, I'll deduct the price of the commission from the price of the next level.
For discounts on commissions, from 20% to 35% off, see my patreon tiers. And if you do the math, you can save more than the price of your patronage in a single commission, and still get all other patron benefits.
