Nikon D800 with free Rode VideoMic Pro Compact Shotgun Mic for $2800
B&H Photo has a variety of Nikon D800 bundles. One of them offers a free Rode VideoMic Pro Compact Shotgun Microphone including automatically with the Nikon D800 kit by B&H Photo and offered at the same price of $2800. No coupon, no rebates. This is a $200+ microphone, not a toy mic!
The Rode microphone itself has a promotion that can get you the Plural Eyes software for free. This is an online process - a PDF file explaining the process is available at the B&H Photo product page. Basically you purchase an eligible Rode microphone for an authorized dealer, receive the microphone, register the Rode online to get the free ten year warranty and then use the information in your RODE warranty confirmation email to download the free software. You don't have to mail anything in and you don't have to cut UPC codes!
