Went looking for some clearance (Viewtiful Joe DS rang up at 14.99) and I saw this had a Temporary Price Cut now through 3/19. I think these deals are chainwide.
I work at Target and I believe TPC's are not chain wide as sometimes when something is on TPC we also have it in our AD for the same, which leads me to believe they are not. However, I could be wrong as I am a lowly team member and never get told anything. ;-)
