$20 is the best price I've seen for the Wii U version. It lacks some features the Xbox and PS3 versions have like Ultimate Team, but I've been wanting it for the tablet play.
3DS, Vita, and PSP are also $19.99 plus shipping. Wii is $29.99 and Xbox 360 and PS3 are $39.99 and should qualify...
A game like this is also a very cheap way to qualify for their extra credit when trading toward a used game promotions. In was trading in a couple things yesterday and bought a copy of Wii Fit for 44 cents to get the extra 30 percent credit.
Ghost Roaster was only available with the Darklight Crypt adventure pack and didn't get a Series 2 release with Giants. From what I've seen it's not easy to find in stores anymore, but not impossible either.
I can't vouch for this game, but I price matched a Skylanders starter kit today (BB - $59.99) and the system automatically gave me the gift card with no problem.
Best Buy also has NBA 2k13 Wii U for $39.99.

The email I received said the sale runs 11AM-7PM today online, but the prices already seem to be valid. Just add a single or triple pack to your cart after adding the starter pack and the discount is applied.
Shipping is extra unless your purchase totals $79 or more. As per below, no...

Appears to be on clearance.
I tried Montgomery Mall, MD, yesterday with no luck. (Google showed limited stock.)
While there, I noticed a couple copies of Forza 4 in the clearance bin for $24.97, and at least one copy of the newest Professor Layton game for $19.97.
If you can find them, Gamestop already has Wario Land, Batallion Wars 2, and Metroid Prime 3 at $19.99 "new," and Kirby at $29.99 regular price. None are all that challenging to find in the Metro DC area.
I noticed some of those (Layton, Spirit Tracks, and Ranger) in a couple Targets in Montgomery County, MD, so it's probably a wider sale. I also noticed Golden Sun was marked down to $19.99 at a local Gamestop this weekend, so that could be a wider price drop.
