I stopped by Shopko (a department store in a few Midwest states comparable to KMart) today in Green Bay, WI and saw a few gaming worthwhile clearance deals. Most of the games I saw on clearance were overpriced or junk titles but there were a few decent deals that I can remember seeing:
Wii U Deluxe w/ Nintendoland - $209.99
Wii Remote Plus (pink and white) - $19.99
Lost in Shadow - Wii - $8.99
These prices may be even better on May 11-12 for the Friends and Family Event. I do not know if there are going to be restrictions but my receipt says 20% off for those days.
I ended up picking up a Wii U so I can get Mario Kart at the end of the month. This system update is taking forever..........
