Bob understands that if you use a coupon to attract a customer, you will have to use them to keep them. And this strategy kills real long-term value for the business and eventually the customer as well. If you are a business owner and thinking of using Groupon or another Groupon clone, you owe it to yourself and your business to read Bob's e-book first. I guarantee you this will be the best money you ever invested in helping you better understand how not to market your business.
