W3 Custom Product Options

I used this app to create complicated price options with conditional logic. It was very easy and intuitive to set up and this App has been able to fulfill every need I have for my store. The support I have received from Justin and Megan has been OUTSTANDING! They respond to my emails very quickly and are very clear with their instructions. I have tried two other Options Apps in Shopify and this one is by far the best and it is affordable.
