Amp Back in Stock | PreOrder

I've been using this app for over a year, and after trying the other similar apps on Shopify, this one is clearly the best. It takes one very important task off your plate: Keeping track of who wants to know when what is back in stock. There really is no reason to try to manage this yourself. All the editable customer emails and reporting are icing on the cake.

I can point to thousands of dollars of sales that this app has generated, and many hours of time saved by not having to manage and notify all those backorder people myself. Worth every penny.
