Infinite Product Options

I have yet to review an app for Shopify, but I just had to for Infinite Options. You'll be completely amazed at how this application is free. It is a simple app and does exactly what you need. However, the customer support is one of the best out of all my apps. They have chat support to answer any of your questions and they helped me fix the coding problems I couldn't solve. They are responsive and they do whatever it takes to optimize it for you. It's amazing all of this is free!
