Businesses are being sold incredibly expensive advertising campaigns that are disguised as “no risk” ways to acquire new customers. In reality, there’s a lot of risk. With a newspaper ad, the maximum you can lose is the amount you paid for the ad. With Groupon, your potential losses can increase with every Groupon customer who walks through the door and put the existence of your business at risk.
Groupon is not an Internet marketing business so much as it is the equivalent of a loan sharking business.
