Amp Back in Stock | Preorder

Generally a very good app. We have been using it for a few years. It works well 99.999% of the time, which is better than most. Once in a million, it does send an erroneous message when the item in question is not back in stock but a message is generated and sent anyway. We tried working out what was causing the error but couldn't pinpoint the problem. As it has only happened on a few isolated instances over the course of a few years, we would still recommend this app overall.
