Pre‑order Manager Pro , 20 reviews

Brilliant app, it's only dropped a star because I can't bulk de-activate pre-orders, and a whole star feels harsh, I'd give 4.5 stars if I could. This is the third pre-order app I've tried, and it's by far the best. This app has two main advantages over others I've tried: the button loads immediately, and the app isn't affecting page load speeds. One of the other apps I tried loaded a script that was a bit slow, so it was possible for customers not to be shown the "Pre-Order" version of the button. Another app I tried added full seconds to page load speeds. This app has none of these problems. On top of that, this app is the easiest to use, it's really intuitive. I emailed the developer a question about how it worked and got an excellent answer right away, too.
