Simple Alerts

This plugin does exactly what we were hoping to do - allow our partners to have alerts for when a product is purchased using their discount/coupon code. There were a couple of customization features that we were hoping to have available, and while they were not initially, the developer is incredible & took swift action to implement these changes very quickly. Excellent support & an easy to navigate interface - 5 stars from us (would be more if we were able to!)
