i picked up MOH Warfighter (14.99), Hitman HD (24.99) and Dishonored (29.99) for PS3 at BestBuy in Avondale, AZ. I actually had to explain what happened to one of the cashiers who was great, checked, called a manager over, who I explained the situation to again, who actually mentioned he'd heard some rumbling on their email system about prices not reflecting correctly - they overrode the pricing right there. Took less than 5 minutes.
Seems very hit and miss. Some people know about it some don't...
