OPTIS Product Options, Variant

OPTIS is a great way to overcome the variation limit default in your Shopify store. This add-on allows very easy integration and customization of your products. I don't like the subscription-based model, especially for smaller businesses such as mine; I have submitted a request to the company to provide another product tier that allows a one-time purchase of the add-on that has a limited number of product customizations. Larger sales volumes can afford a monthly add-on but some of us need to grow into that capability and would be better served by a single purchase until we get there. Subscription aside, the product itself is very good and useful.
