Today and tomorrow while supplies last, Best Buy has Wii U games and the console itself on sale. The system is the Basic Set, marked down from $299.99 to $249.99 for this promo. For the time being (at least in the US), I'm not sure you're going to get much better than that.
As for the games, there's more of a selection. The line-up includes: Darksiders II ($19.99), Ninja Gaiden 3: Razor's Edge ($29.99), Nintendo Land ($29.99), Batman: Arkham City Armored Edition ($34.99), Call of Duty: Black Ops II ($39.99), Assassin's Creed III ($39.99), ZombiU ($39.99), and Skylanders Giants Starter Pack ($54.99).
At that price, you really ought to consider picking up ZombiU.
