NOTE: These rebates ended on August 28th. Nikon announced a new instant rebate program that runs through October 3, 2015
Nikon is currently offering some great instant rebates that can save you between $50 to $900 on select Cameras and lenses from Nikon. Unfortunately Nikon has not specified an ending date so this promotion can end at any time. Instant rebates are great because the rebate is handled by the dealer. You don’t have to mail in paperwork and receipts, wait for a check and jump through hoops. You will find a link to Amazon to purchase under each item.
