OPTIS Product Options, Variant

I have had this app for about a month. 5 out of 5 stars. Easy to use and the customer service is unbelievably fast and accurate. I needed a little help getting the options to show on the customer's order confirmation, they took care of it very quickly. I needed help getting the option to show in the new order emails to my staff, they took care of it very quickly. I cannot recommend this app enough if you sell personalized products like we do. It even plays nice with shopify's product variants.
