Groupon has grown like wild fire recently and has really become a major player in the mobile world. The app is extremely simple to understand. It offers daily deals on all kinds of local products and services.
The service is available in most major cities now and really does bring an interesting look into coupons as a service. Instead of providing a list of available deals in your area, the app has only a few deals a day. Each deal is usually very specific and only available for a day. This is very similar to a lot of online sites like woot.com but instead offers more of a coupon perspective than a sales perspective.
The idea is that you’ll see a great deal on the app, you’ll purchase it, and then bring the digital coupon to the store that offered the deal and redeem it by showing them your phone. Although I haven't really found any deals that appealed to me in the time I’ve known about this app, I definitely could see how it could be a huge tool for finding great deals. Definitely download it and see what’s in your area.
