If you don't already have a Canon EF 24-105mm f/4L IS USM Lens, the kit is a great value even without the B&H deal.
Make this deal even hotter by adding a Canon PIXMA PRO-100 Printer plus paper to your cart at the same time. The camera and printer combination qualifies for a $400.00 rebate, which completely covers the cost of the printer. The included 50 Sheets of 13 x 19" Canon SG-201 Semi-Gloss Photo Paper Plus has a $44.45 value.
Don't need the printer? Sell it on eBay to take another chunk off of the 6D price tag.
