Right now, Groupon is offering 20% off Local deals with the code SALE3! You can usually get some awesome savings on things like restaurants, family activities, massages, spas, and so much in your area during these sales! I just picked up FOUR admission passes to a local amusement park for only $71.20 with this deal, and admission is normally around $50 PER PERSON!
You can use this code once per transaction and up to three times per account. The same code will also give you 10% off up to three Goods deals and 10% off up to three Getaway deals.
