And this week they launched another. The $109 Kindle Essentials Bundle combines the basic Kindle with a USB power supply and a case. The case comes in your choice of six colors (black, pink, red, yellow, blue, or purple), and normally retails for $29 (overpriced, if you ask me).
With the basic Kindle retailing at $79 and up, this bundle essentially includes a free charger. That's not bad, but you can find chargers for $5 (or just use one of the ones lying around the house).
If you want a recommendation, I would go for the Kindle for Kids bundle. It costs $10 less, and that two year warranty could come in handy.
