A little about Groupon: Every day there is a "Deal of the Day", which typically is around 40-60% of the retail value. There have been deals on things from massages to pizza. It's easy to purchase and easy to use! You purchase online, print online and take to the business to use. And you can even buy them and give them as gifts!
