Quick Stock Notifier ‑ Instock

I have been through a few apps which offer the ability to notify customers when items are back in stock. None of them really fitted the bill as they often wouldn't support multiple inventory locations (if they did it was for an exorbitant fee). The guys behind this app have been great from the start, helping me get it all set up and making a few tweaks here and there. It works really well, customers get notified almost instantly (1 app I tried took over 6 hours to alert the customer - by then the products were all out of stock again). Great app which works, great team and great experience - thanks :-)
