Groupon is quickly becoming the Zappos of the coupon industry. The cited article by Jackie Huba highlights 9 ways Groupon is doing this:

1. Promote the Fine Print - Everything you need to know is front and center…as it should be if you need to know it.

2. Put a Phone Number on every Coupon - Got a problem? Call the number, day or night. They keep the focus on customer service.

3. Anticipate and Diffuse Frustration - Mistakes will always happen and Groupon makes it a priority to deal with them…and they also have a function on their site that lets you punish “Derrick” by pushing a button that prompts a video of “Derrick” getting a drink thrown in his face.

Key Takeaway: Their customer service is their priority. That is why they are loved by their customers and are growing so rapidly.
