Got this email from the THQ Online Store. Doesn’t look like the sale is live yet.
Purchase between 5:00 p.m. Pacific time on Wednesday November 23rd and midnight Pacific time on Monday November 28th and receive up to 50% off console and digital catalog titles including Warhammer 40:000 Dawn of War, Company of Heroes, Penguins of Madagascar and more.
Or buy Saints Row: The Third or WWE’12 and receive a $20 store credit toward your next shopTHQ purchase. U.S. orders are also eligible for free standard shipping.
I believe the sale should start within 30 minutes or so.
