Picked up MadWorld for $9.97. They also had a Xbox 360 HD-DVD add-on, but I was unable to get a price check. (The electronics guy was dead or something and no one else would scan it for me)
Pikmin Wii was also $9.97, but I already have the GC version.
The one local Sears had an HD-DVD drive sitting in the case forever and every time I had it price checked it came up $49.99. One day it just disappeared. Either they FINALLY did the updates on it and had to junk it out or someone actually bought it.
I've had to go to other sections of the store before to get someone paged to come to electronics and get the keys to open the case to price check stuff before. Be persistent if you really want something price checked.
