Keep in mind that anyone advertising a significantly lower discount than Adorama, B&H, or Calumet is likely stripping batteries, chargers, manuals, Nikkor lenses, and accessories out of the boxes and charging you full retail price to buy them when you open the box and discover them missing.
Nikon USA [along with all other camera makers] runs a tight ship on their dealers and will not let them discount the product like appliances or cars. The larger authorized dealers sell enough product that Nikon USA allows them to discount a bit more than a single local retailer.
If anyone advertises 30, 40, or more percent off the MSRP as shown on Nikon's website, be VERY leery. They will either steal the accessories or you will never see the camera you ordered.
