I looked at the $400 deal from the new amazon seller (which is gone by the way), because it looked like maybe too good a deal also. What I found interesting was looking at this sellers other items for sale. Among them was a brand new Canon EOS-1D Mark II 8.2MP Digital SLR, which normally goes for about $4,500.00 from reputable discount camera dealers.
If my memory serves me, this person was selling it new for about half the going rate. When I looked at other sellers, the cheapest was for a brand new camera at $990.00. Now that I think about it, I've been wanting to upgrade to a digital SLR . . . .
What is also interesting is that many of the sellers for that item also claim they don't take amazon payments. It looks to me like potential fraud being conducted over amazon is bigger than I ever thought possible.
