Price drop on this auction: eBay
has the Canon EOS 5D Mark III DSLR Body
for only $3,147.68 shipped (comp at $3,499.00). Plus, "You'll earn $62.95 in eBay Bucks."
Update: Friend of the site Noah informed me that, as of 6/3/2012, seller "BuyItDigital" is not on Canon's authorized retailer list
and that a warranty card is not listed as being included. I've never needed a warranty card for repair service, but the non-authorized-retailer is more of an uncertainty in my mind. BuyItDigital has a very high eBay feedback rating.
Noah adds that Canon authorized dealer The Imaging World
has the Canon EOS 5D Mark III
for only $3,218.00 shipped. "You'll earn $64.36 in eBay Bucks."
