William Walker review for PreOrder Now Backorder WOD

I have now been using this app for a few years. When it works its a good app. However, it is a ticking bomb. I just noticed that all out of a sudden normal available products were shown as preorder products whereas products that have stock below zero were shown as available. What is even wore, the mixed cart pop that was triggering on every page reload, was supposed to be fixed after i have submitted a ticket. I just realized that it is not fixed and customers had to close the pop up on every page reload. This plugin did more harm than good. Please look out for a more stable plugin, as this plugin will cost you a lot of money......
