Notify! Back in Stock|PreOrder

I have been using the Notify! app for about a year now and have been completely satisfied with the implementation and results. For the 1st year, we only used the Notify Me When Back in Stock function, which has worked well with helpful reports, but we've just added their new Pre-Order widget and everything was seamless with excellent help from Nareh on the support team to make minor adjustments and see to our complete satisfaction.
