Heck, I bought a Windows Phone off HSN because it was a good deal. Lots of people out there are still rocking the S2. It was the biggest seller for Samsung IIRC. If you don't mind not having the latest and greatest, depending on your uses, this may be a killer deal for you.
That said, you may be able to pick up a gently used one from Swappa even cheaper. Check that out as well.
