A1: back in stock | sms alerts

I needed a way for my customers to be notified when stock is out. I don't have enough help to track and send the emails myself. When I asked a Shopify Guru, they pointed me to Back in Stock, and I'm SO GLAD THEY DID!
The app is easy to use and very customizable. BONUS PLUS, the customer service is AMAZING!! Someone is always around to chat and answer questions quickly and walk you through whatever you are struggling with.
I wish all the apps were run this way. Thanks so much Back in Stock!!
