DPO Dynamic Product Options

The interface took a day or so to understand and get the hang of. I have a large catalog with a lot of products with complex options. I needed an app that would be able to apply options conditionally at the variant level, and be compatible with the Downpay app. This one actually was able to accomplish all of the above and looks seamless on my site. The Shopify 2.0 integration also means it loads faster than my old app (Advanced Product Options). Roman was incredibly helpful with the setup, adding code to the template to be sure it works as I need it to. Very happy!
