The official "The Mid-November Half Price Source Code Sale" is being extended through tomorrow - Monday, November 26th.
Because it is "Cyber Monday". And that's as good a reason as any!
Here are the details:
Between now and Sunday, the 25th (the Sunday after Thanksgiving), you can purchase GPL or BSD licensed source code for half price. This includes Illumination Software Creator, Linux Tycoon, BLABA, 2299 and the RB Dev Pack.
To sweeten the pot, everyone who picks up a source code license -- for any of these games and apps -- will receive a subscription to "Illumination Software Creator : THE BOOK".
