Mst: Preorder + Back in stock

Kundan and the team at Now in stock @ $3 have the best bang for the buck for dealing with out of stock products. They have recently added a feature that allows us to exclude certain variations or entire SKU families we never plan to re-stock from future notifications. The team has been quick to respond to questions and suggestions. I rate the app as a B+ and four stars for their very good customer support.
