ExcellentSupply.com review for King Product Options, Variants

I have tried a handful of paid apps for product options, and all of them have been wonky! All the ones I tried looked horrible on our store, and for no apparent reason would fail to work on various browsers. This one clearly is the BEST (as their name implies). Works flawlessly and looks great too. After trying so many flops I can't believe such a well-mannered options app exists — and it's free. Shopify should purchase this app and make it part of their package. Yep — it's that good. Kudos to the developers! Highly recommended.
