A local dental practice decides to run a Groupon campaign. The campaign offered $350 worth of dental services (such as teeth whitening) for $150. For the total campaign, 260 coupons were sold. We estimate that 85% of the coupons will be redeemed, that 35% of the coupons will be redeemed byexisting customers and that, on average, Groupon customers purchased 1.5coupons. Let's assume that 20% of newcustomers come back after the Groupon coupon visit. The dental practice estimates its cost of goods sold to be 60%. Finally, the bill for the average Groupon customer was $380. The dental practice negotiated a 50/50 split with Groupon.
