The current US Nikon rebate program ends this Saturday (June 26th). It seems that Nikon will extend the rebate program in the US for another month but with some adjustments. For example: the 10-24mm lens will not qualify for a rebate and the 70-300 lens rebate may go down to $100.
The US rebate program started back in March 2010 and this will be its fourth extension. With every extension some products are dropped or rebate amounts reduced.
The current Nikon rebate program in France is valid till the end of July.
