Preorder, Back In Stock ‑ STOQ

This app is amazing. We needed a robust 'back in stock' system in place with a bit more customization that we couldn't achieve in our email marketing app. RESTOCK ROCKET is THE APP TO GET! We were up and running in 20 minutes, and had one of their devs make changes to the look/feel for us so that it matches our brand. SUPER HAPPY! You can't go wrong with these guys.
