Notify Me! Back in Stock Alert

It is the first app to use for the purpose of preorder and whitelists, and I am overwhelmed by their great service.
first, they have a package for small business that didn't pass 1-year on Shopify

Second, once I requested check for eligibility of the small business package, I was welcomed and served by representative called Nilou which offered all the things that can make my website better before I am thinking of anything, everything was set up for me and adjusted to suit my website

great job guys!
