HA Product Options Variants

It's Great App,and it helps me so much.I am a seller focusing on sportswear customization. In order to customize product option, I found a lot of apps, but most of them are not supported or require more money. Fortunately, I found this app"Infinite Product Options", which meets most of my needs, and the most important thing is that it can add product custom prices to the shopping cart. I encountered some trouble during the process of setting up the app, and their staff responded quickly. Very fast, and to solve my problem, thank them again.Eric
