DPO Dynamic Product Options

I wanted to wait until our shop went live before leaving a review. We only have 4 main products but each has between 150 and 650 variations -- we make them to order. Itoris Support went above and beyond expectations. From the initial set up, to helping with clear instructions on setting up all those variants, to helping with a hiccup or two once we launched. I would highly recommend this app. PLUS, one of the very few out there that will allow an option/variable to subtract from your "main" price.
