One of the nicest options of ASUS' line of tablets is the keyboard dock with a built-in extra battery that can make your device run forever and much easier to type on. The downside? Those docks tend to cost over $100. In the case of the Transformer Pad 300 (TF300), exactly $127, to be precise. Right now, though, Newegg is offering it for free if you buy it with the tablet. The deal is available in both blue and white options.
Be sure to check the "2 Item Combo" check box. If you attempt to add the two accessories separately, you won't get the discount.
