KartDiscount ‑ Coupon on Cart

This app really helps improve conversions. It does two things: (1) it shows the applied discount on the cart page, and (2) it allows customers to combine/stack both manual and automatic discounts . Store owners can control the way discounts can be combined. Customer service is generally responsive if you allow for timezone delay (they are based in India). When I discovered a bug in the app, customer service fixed it within a few days. I only have one niggle / suggestion for improvement: notifications to customers (e.g about minimum order values) are shown for only a very brief moment. It would be good if the display duration of notifications could be edited.
