Special pricing - I'd recommend pouncing for $2.50.
Great price!
p.s. If you already own Magicka, looks like there is some new and free DLC.

I wonder if they've fixed the video issues that quite a few have had, yet? I kinda gave up on checking after awhile. :'(
They certainly put DLC out at a blistering pace.
