Think of LivingSocial as a Groupon-esque guide to sniffing out steals wherever you've set up stakes for the evening. Focusing mainly on dining and entertainment, the LivingSocial app shows featured limited-time deals in the surrounding area. Don't feel like bringing your credit card to an unfamiliar venue? LivingSocial even lets you pay online for some orders. Gone are the days of leafing through the AAA book or settling on the local dive to find a good meal deal on the road.
