Alert Me! Restock Alerts

*This is a follow up review on the app, the app works and we are very happy with it. The support was slow to reply but now all is okay. It is very unfortunate we have to write this review. The app seems great, we have had some problems after custom installing on our store. We received one email back from support after we sent many. We had been informed they would help ASAP. However after many more emails we got no reply from them. Very poor service, we will update our review if we get help on this matter.
