Photoshop CS6 For $200 at Amazon

My guess is that it was because I had bought the CS5 Upgrde from Amazon when it came out three years ago (or whenever). I think this because just yesterday I got another offfer from Amazon via email to buy Illustrator CS6 for ~$250, and I had bought the Illustrator CS5 Upgrade as well. I am hoping that they send me a similar offer for InDesign CS6, but I haven't Upgraded that since CS3. We'll see.
