APO Product Options, Variants

My store is BullhideBelts.com and all our items are custom made so we have many options for each belt. The Advanced Options app from MageWorx is really great and allows us to create many options and swatches to make checkout and choosing options really easy for customers. I have tried 4 options apps in the past 6 months and this one is by far the best. They also are responsive to emails quickly but I wasn't able to get them by phone at all.
