They could be doing something like trying to buy things from places like www.harmanaudiooutlet.com and then make you THINK you're getting a deal for a NIB product at 1/3 off. But that's just a theory.
Never Used -- in Sealed Box
Who are the people who keep buying audio equipment, then offering it for sale without even opening the box?

Or do they believe that perhaps we are interested in buying some?
