I work in this space and we have received feedback on Groupon from hundreds of merchants. In many cases they were not happy with their promotions for the following reasons: 1) Groupon didn't adhere to the sales limits and oversold vouchers 2) Once the promotion was set in stone (a few months before it ran) the sales reps for Groupon were unreachable. Additionally, merchants could not contact sales reps to run another promotion. 3) Customer retention was very low. I agree with the comments in the article that the sales force has no idea what is going on operationally. Really all they care about is inking the next deal so they get paid while all other considerations for proper customer service and the well being of the merchant fly out the window.
