Nikon now has 3 different rebates available – here is more info. The lenses applicable for this rebate are:
AF-S DX Zoom-NIKKOR 55-200mm f/4-5.6G ED
Now the offer has changed from mail-in rebate to instant savings:
$100 with Nikon D40, D60 or D80 digital SLR camera
$150 with Nikon D3, D300, D200 digital SLR or an F6 35mm SLR camera body
Unfortunately Nikon dropped the rebate on the Nikon 18-200mm f/3.5-5.6 G ED-IF AF-S VR DX Zoom-Nikkor Lens.
