For the next week Steam users can purchase Guacamelee! Gold Edition, Hotline Miami, The Stanley Parable, Octodad: Dadliest Catch, Monaco: What's Yours Is Mine and Fract OSC for a grand total of £15 / $20 as part of the Indie Megabooth - Solid Gold Collection.
Typically all of these games combined would cost a total of £61.94 / $85. Most of these titles are available for PC, Mac and Linux, with the exception of The Stanley Parable and Fract OSC, which don't support Linux.
This offer is only good until midnight on Monday 3rd September, so you'd best snag this quick if you're interested.
For the uninitiated, the Megabooth is an indie collection at PAX wherein dozens of developers pool together to showcase their wares over a sizable chunk of the showfloor. This current Steam bundle is to commemorate PAX Prime this weekend where these games were once part of the Megabooth. Other alums include cult hits like Don't Starve, Super T.I.M.E. Force, and Papers, Please.
