Apple MagSafe Airline [Power] Adapter for $45

Need to power up your MacBook or MacBook Pro on the plane? I have an unused, open package Apple MagSafe Airline Adapter for sale; $45 because it's open (normally $49 + tax in stores). Just a note: this only powers your MacBook/MacBook Pro and does not recharge the battery. Also, this adapter only works with airline in-seat EmPower and 20mm power ports; a separate accessory is needed for powering from a car.
