TV wall mount bracket (SANUS VMAA18, full motion, for 30-52 inch TVs)

I have this TV wall mount bracket, Sanus Systems VMAA18B (BLACK) Universal 30-50 Inch Flat Panel Mount with 18 Inch, Swing ARM wall mount.
This can hold 30-50 inches flat TV. Full Motion. This is a left-over from the TV set I bought last year.
I am moving soon so want to get rid of this asap.
I see the lowest price on the web for a new one is from $184 to even $380.
I am asking $80.
