The price is not too bad, but it is not cheap either. Check this website daily. They always have good deals. Looks like this one is the same as your Walmart model. On the mainpage it is advertized for $99. Give them a call and refer to the offering on the main page.

BTW: I myself would prefer smaller models - like 500GBs. The bigger they are, the more cumbersome they are too - e.g. for formatting. And filling even 500GB will take quite a while. By that time, they may have better and cheaper models.
