DPO Dynamic Product Options

This is the only product option app that I've tried that doesn't cause problems, and price changes without me changing anything in the app myself.

I tried a lot of product option apps trying to get anything to work consistently. This is also the only one that has allowed me to get even the most basic version of what I want, and the developer has gone above and beyond to help me with weird ideas that have exponentially gone beyond what I originally wanted.

I highly recommend giving it a try
