If you are looking to buy either the Nikon D800 or the D800E body only kits, there is a three-layer stackable promotion at Amazon. Start at the free accessories promotion page: add either the D800 or the D800E and all three of the accessories (Extreme SDHC, extra Nikon EN-EL15 battery, AmazonBasics SLR backpack). This promotion ends 6/30/13.
The second layer is optional - you can take advantage of the stackable Nikon Instant Rebates. This promotion ends 6/29/13.
The third layer is automatic - a 4% instant reward discount on qualifying purchases applied in the shopping cart on the total amount (before the discounts are factored in!). The 4% promotion ends 6/15/13.
In our guinea-pig example here we added the Nikon D800 ($2800), the 24-70/2.8 ($1890), the 70-200/2.8 ($2400) and the three free accessories ($55, $34, $30) to the shopping cart. Then proceeded to the Amazon Checkout page. The top right corner of the Amazon Checkout page looks like this:
The -$283.40 is a 4% discount on all eligible items. The -$300 and -$200 are the Nikon Instant Rebates on the 70-200 and 24-70 lenses. The three smaller amounts (with green lines to their left) are the three free accessories (backpack, SDHC, battery).
Because of the 4% instant rewards, factored in the total price is an additional 4% discount on the instant rebate discount, since the 4% is on the full price of the lenses, not the discounted after combined purchase instant rebates. In our case, the $500 is subtracted after the 4% discount, so built-into the $283.40 discount is an additional $20 discount (4% of $500).
