It was only a few months ago that Facebook rolled out Check-In Deals which allowed you to gain access to special offers when you check in at a local business from your mobile. Deals on Facebook is a step further which lets you help find fun experiences to share with your favorite people.
Deals on Facebook is currently limited to just a few US-based cities: Atlanta, Austin, Dallas, San Diego and San Fransisco. Facebook have worked with partners and local businesses to help deliver the best social activities in your area. Once you've found a deal that you like, you can then share the activity to friends, buy it and plan it all from Facebook.
Facebook lists the upcoming Austin City Limits Live, where they're offering an "All Access Experience" for concerts starting in May. You could buy this deal, get a backstage pass, sound check access and a catered dinner in addition to attending the actual show.
Facebook are also working with aDealio, Gilt City, HomeRun, kgb deals, OpenTable, Plum District, PopSugar City, ReachLocal, Tippr, viagogo, and zozi, so you can buy their Deals on Facebook too.
