DPO Dynamic Product Options

I needed an app that could link product options to inventory and this app proved perfect. The customer support is also amazing. For example, I sell a case of jam (12 jars) where the customer can choose their mix of flavors. I couldn't figure out how to make sure the customer could not make a mistake and choose less or more than 12 jars. Customer support quickly helped out even writing a snippet of code so things worked exactly how I wanted them to. Excellent app. Excellent support.
