Groupon can offer such steep discounts because it guarantees business owners a minimum return on their investment and the possibility of becoming an overnight sensation. Groupon claims that its service is a win-win for both businesses and consumers, but there are some disadvantages.

How does Groupon get such good deals?

Groupon earns its money through a commission it generates on every coupon it sells. Retailers and businesses that offer their goods and services on the site are promised a minimum number of deals that are sold. When that threshold is reached, each deal coupon that is sold earns Groupon a 50% commission.
