Groupon is a large group buying site that is gaining quickly in popularity. You can score some great deals on some items that you would typically not purchase due to their price - or save on items you would have purchased anyway!
Each day a new deal is featured in your local area. In addition to this deal, there are many national deals available each day. These deals are typically internet based so that no matter where you are located in the country you can take advantage of it.
When you purchase a "Groupon" it will be in the form of a coupon code that you can use. It will show up in "My Stuff". Therefore there is no shipping on the prices.
Once you join Groupon, make sure you refer your friends over to it as well - especially if there is something amazing going on there! Everytime you refer a friend who makes a purchase, you earn $10!
