I noticed the same listings which adds to the oddness, all but 1 listing is from users with 0 rating on the account.
The only notable difference is they are auctions and not buy it now.
At the very minimum, of the are real listings, they would have to be a bunch of product that managed to "fall off a truck" while that big snowstorm ripped through the West Coast.
Yes, the biggest problem was that the price itself was too good to be true. Anything like that just screams dirty to me, and so I am very cautious about trusting those sorts of deals.
