Update update:
And we've heard confirmation from Valve that the issue is fixed!
Update:
As people have noted, this is a store-wide issue, so you can rest assured that Valve is working to fix it as soon as possible. I'll leave this announcement up as reminder of the discount in the mean time.
Original post:
As some of you may have noticed, the 34% discount that should be running from now until 2/2 has been disappearing and reappearing from the site.
We're currently working with our Steam reps to resolve this, so please check back again soon if you didn't get a chance to buy it at discount yet.
We'll update here once we can confirm the problem is fixed.
