Amp Back in Stock | PreOrder

We love this app. Due to lots of unforeseen issues, we tend to run out of stock on products. This app helps us recapture lost sales regularly. It is probably the app we find the most value in out of all of our Shopify apps. It works well and the support is great. I only wish we could add BIS alerts to individual variants without additional theme support. Other than that, we find it enormously helpful and recommend it.
