Variant Option Product Options

I had a few issues with this app at first - it wasn't functioning properly with a wholesale app that I was using. I uninstalled it, thinking that like many devs it would be impossible to reach these folks, and to my surprise and pleasure I was contacted almost immediately asking if they could help. I explained the problem and the dev fixed it almost immediately. Needless to say, I'm using this app now and wouldn't look anywhere else. Great app, great service!
