Coupon X: Discount Code Pop Up

Excellent app! I wanted a simple discount pop up for my new customers who sign up to my mailing list. The app is super easy to use, and the widgets are so easy to create.
I managed to get my pop up running in less than 30 minutes. It generates new codes each time so that the customers cannot abuse the discounts and recognises when an email address is entered more than once.
Good value for money, too.
Also, the team are available if you need them with the chatway system.
