APO Product Options, Variants

After 13+ years of custom building bags with hacks and patches to give my customers the chance to get the fabric / color combo they wanted on our site, I found this plugin (yesterday), and as of this writing, it is now fully in place and serving marvelously. BUT...
It is the customer support / service during integration that blew my mind. VERY fast! Angie solved my initial problem, then kept the dialogue open, helping me close out additional concerns as I worked to integrate it. Just get this. Seriously.
