Turbo XL review for Notify Me! Back in Stock Alert

expensive for what it does and too many pay to unlock features which should simply be included. I had 1 qty of an item that was back in stock which sent out 600 sms notifications. I lost money on the sale. I will only use this until im back in stock to honor notifications to people that have signed up but will move on from this after. It's really an app for larger stores that make at least 1000 sales.
