It’s just a weekly sale. There are some really good deals, I picked up several point-and-click adventure games that I’ve had on my “someday” list for <$2 each.
Still Life 0.99
Still Life 2 0.99
Post Mortem 0.99
Atlantis: The Lost Tales 1.19
Atlantis 2: Beyond Atlantis 0.99
Atlantis 3: The New World 0.99
Dracula 4+5 1.99
Dracula Trilogy 0.99
Richard & Alice 1.19
Subject 13 0.99
Many other good games, several of which I already owned. Worth checking out.
Dracula trilogy a whole dollar less than what I bought it for (thinking it was a good <2$ deal 6 months ago)?! And still I haven’t played it.
Aargh!
This one looks interesting. I might pick it.
Think about me buying Grim Fandango for a lot (okay, it wasn’t that much to start with but just a minor reduction) and then GOG giving it away for free! 
I never ended up playing it at the time because the OpenGL did something odd on my Linux and I neglected to install it on Windows.
