Preorder, Back In Stock ‑ STOQ

I just got the app, but with already setting up the parts that are not stocked and a 3-5 day wait time, let alone the items out of stock to have them set to pre-order, this is going to be SO HELPFUL. The customer support team has already been great to deal with as well. Was having a plug-in issue with our website theme and they fixed it very quickly.
