APO Product Options, Variants

App does what it says most of the time, I can't complain about that. However this app broke one of my more complex implementations, and is presently allowing either one of two functionalities:
1) customers can buy expensive items for $0.00
2) customers cannot add item to cart at all

Support has been completely unresponsive for at least 12 hours now, including a Chat rep who just said "open a ticket" and then immediately closed the chat on me. I would honestly tolerate this under normal circumstances, however it's BFCM Week and any app vendor who isn't beefing up its support this week is one that clearly doesn't have its customers in mind.

I tried a few other product options apps, but advanced product options was by far the best. Also the support is super fast and competent.

this app is what I'm looking for all along, the customer service is top notch, helping me on every single details & very fast response! really recommended and very happy to use this app!

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.

This app is invaluable to our website! Without it, I could have never switched from WooCommerce to Shopify because of our needs for customizations, customer uploads, etc. This app gives us all of the abilities for our customers to customize and makes creating new product listings incredibly easy. I've also had a couple of instances of needing support from the developer, and I've received a response to my request AND the issue addressed within a few hours each time. I'm so impressed with this level of service! Very thankful for this app and the team!

This app has been great...lots of flexibility to fit our needs and the support has always been fantastic. Glad we found it!

This app is very helpful! And the team is amazing! Always answering as quickly as possible and always help me out with the issues.

Great app with plenty of possibilties! Support is amazing, and extremely helpful to get it exactly as I wanted it to be with very quick responses. Highly recommended!

Buyer beware!!!
Although the support has been helpful (to a point), I'm now left waiting of major bugs to be fixed and cannot sell on my store. The app will not remove variants from the cart meaning if a customer removes am item from their cart, the options still remain and cannot be removed. This app does not play nice with Shopify and I'll be asking for a full refund.

The app does exactly as described, and does it well. The conditional logic is excellent and gives plenty of flexibility to enable me to control the various allowed permutations of my options. Their support is top class. I had a minor niggle when I moved to one of the Shopify 2.0 themes so e-mailed MageWorx and got a response mere minutes later, and resolution by the following day. They couldn't have been any better!
