Living Social, the hugely-popular online coupon company, is offering dollar lunches around San Francisco today, and today ONLY. In order to cash in on this insane deal, simply head over to the Living Social website and sign up for a free membership. But don’t delay, the deal’s only valid from 11 until 2PM. The one-time offer celebrates the arrival of their Instant Deals promotion, allowing users to find local discounts in realtime.

“We are excited to launch LivingSocial Instant Deals in a city known for both cutting-edge technology and fantastic food,” said Tim O’Shaughnessy, chief executive and co-founder of LivingSocial, in a statement.

There may be no such thing as a free lunch, but for today–at least–this is the next best thing. You have only a few hours, don’t delay! Commemorate Brian Wilson’s winning performance in the All-Star game last night, by doing a little #winning of your own.
