Groupon is a website where they have a different deal each day. Most of the deals are for restaurant and other retailers certificates at a great discount. The nearest location is Minneapolis/St. Paul, but there are some deals that are online deals. It is also useful to check other locations if you are planning on traveling, to find deals to try to cut some of your travel expenses. Today is the first time I have taken advantage of one of their deals. The deal today is for $25 get a certificate good for $50 worth of merchandise at GAP stores (sale items included). This is one deal that is good at any GAP store in the US. Another deal they have today is for an online nut store.
You sign up for an account and can register to receive notice of the deals each day. This is one way to try different merchants at a reduced price or get a deal on places you usually frequent.
There have been stories of people trying to live a year or so by only using Groupon coupons.
