Best Buy Employees Fake Wii Scarcity

"Apparently, some Best Buy out in New Jersey has been trying to pull the wool over the eyes of their patrons, with a single employee prowling the store, claiming to have the "very last Wii." Of course, someone snatched it up with the quickness, but not 30 minutes later, another employee was at it again, prowling the store looking for another customer to snatch the console from them. There was even an announcement on the PA system. The tipster even said he overheard two manager types discussing the "sales technique," deciding on when they should send out the next Wii."
