There are currently several rebates available for Nikon DSLR and lens packages, including the D800, D4 and D7000.

The Nikon D7000 is available with a $100 instant rebate as well as additional discounts on lenses such as the AF-S 55-300mm ($150 off), AF-S 18-200mm ($150 off), AF-S 24-70mm f/2.8G ($200 off) and AF-S 70-200mm f/2.8G VR II ($200 off).

You can choose either the D7000 body only or the D7000 w/ 18-105mm kit lens.  To take advantage of the bundle rebates, click the "Buy Together and Save" link on the B&H product page.

There's a similar deal for the Nikon D800 and D800E.  Clicking the "Buy Together and Save" link will let you bundle the 24-70mm or 70-200mm lenses with $200 for each lens.  In addition, B&H currently is bundling free 77mm Tiffen UV and Circular Polarizer filters with the deal.

The exact same deal applies with the Nikon D4 as with the D800.

These instant rebates are set to expire on July 28, 2012.
