Locksmith

Works well with lots of options for different scenarios. Can be complex to set up but if you have a question, a real person will respond to you very quickly with good advice. It's expensive considering that basic locking features should come with every Shopify plan, in my opinion. The search tool to start a new lock can be very slow, to the point where it freezes completely. Apparently this is a problem on Shopify's end, but I wish that there was a way to filter before beginning a search; such as, search only products (or collections) for the term ___. I also wish you could lock tags. All that said, we've been using the app for over a year now with no problems.
