Essent Preorder Back in Stock

I just started using this app and for someone like me who is not the most tech savvy person, the app was easy to use and set up. I did need some help with the preorder button for my theme and Matas was able to quickly fix this issue. I think this app will be a great addition to my store. I special order many items for customers as I don't want to stock them and this app should help with my operation.
