Today at noon, presale tickets for the 2013 Virgin Mobile FreeFest go on sale on Ticketfly.com. Prior Virgin Mobile Festival ticket buyers, Virgin Mobile customers, and Virgin Mobile Facebook and Twitter followers will receive access codes for today’s sales blitz.

So bookmark and refresh this page!

If you miss out, relax: You can still grub up your Robin Thicke Vampire Brothers tickets during the general sale Friday at noon. Miss that one, too? Non-free tickets will be available Friday at the 9:30 Club and Merriweather Post Pavilion box offices for $49.50 apiece.

Late and broke? Wait. The festival may release more tickets in the next week or so as part of its “Free.I.P.” offer, which awards tickets for volunteer hours.

Virgin Mobile FreeFest goes down Sept. 21 at Merriweather. Robin Thicke, Vampire Weekend, MGMT, and The Avett Brothers are among the big draws.
