Preorder, Back In Stock ‑ STOQ

It does what it says, and it does it well. I installed it and got it running with no problem with my theme and no impact on site speed. The buttons created by the app were just a little different from my theme. I asked the developer if there was anything they could do to make them perfect. They made the changes in less than 12 hours. I could not be happier. Of all your choices for back in stock alerts, this is the best app by far.
