The team for Smart Coupons is incredibly helpful, responsive, and thorough.
We had an issue with our coupons not rendering and the team replied within hours. They worked with me over a series of weeks while we diagnosed the cause of the issue. After the most recent update, our coupons are rendering once again and our customers are getting the experience they are used to.
I highly recommend the plugin and want to give props to the support team. I give them a 5 star rating.
