UPDATE on Monday, January 31, 2011: Deals is now also available in Canada, France, Germany, Italy, Spain and the UK. Look for yellow or green tickets when you check in to places in those countries. We also launched a new Deals page at [facebook.com...] where you can learn more and find deals being offered near you.
I guess you have to be the kind of person to want to be bothered to 'check in.' I doubt i'll ever live my life around check-ins.
