Groupon's business model involves offering daily deals or "groupons" for goods and services provided by local businesses. Merchants pay Groupon a commission (around 50%) for promoting their deals to Groupon's email subscribers. This provides marketing benefits to merchants without upfront costs. While it generates buzz and discounts for customers, critics argue it relies on short-term price sensitivity rather than building long-term customer loyalty. Groupon faces competition from other daily deal sites that may adapt the group buying model in different ways such as localized sales teams.
