trade-in discount on Surface Pro 3

Microsoft is offering trade in credit for older tablet devices when you buy a Surface Pro 3. I went to my local Best Buy yesterday with an original RT (unused, collecting dust) and a Surface 2. I got $393 credit for the two of them, bringing the price of my Pro 3 down to $606. I think this is a screaming deal. If anyone is thinking about a Pro 3, take your old tablets in and see what you can get.
