Office Depot has JBL E50BT headphones on clearance for $44.94. Brickseek showed zero in stock, they had 2 in stock locally. Saw it when I was buying a printer on clearance that also showed zero stock.
Your mileage may vary. As stated before brickseek showed zero stock but the store had them. The guy at office depot said once it goes on clearance it is removed from inventory which is why it shows not in stock.
