Amp Back in Stock | Preorder

I can not recommend this app at all and I would stay far away from it.
It is super expensive and have only functioned as it should for about one month in total - we have used it for over 1 year and it has caused us SOO much problems and the chat support is very unresponsive. A majority of the months we have used it the Back in Stock function has not worked/showed on the site. Stay away from this app - there are 10 other apps doing the same thing for a fraction of the price.
