LivingSocial cuts 30% off orders under $100 via coupon code "SUMMER". That's better than last week's 30% off mention (which only applied to Father's Day deals), and one of the best general use discounts we've seen from LivingSocial. (For further comparison, we saw $50 off orders of $50 or more last month; however, that lasted about an hour.) Some exclusions apply. Deal ends June 22.
