I would not count on any type of Black Friday deals on these either (especially not from Amazon, who has only had special deals on models on their way out the door, such as the big discounts on the DX, which is now gone from the lineup). The only "deals" I've seen on ereaders for BF are one or two "with gift card" deals at local stores and you'll have to brave the BF traffic and crowds and hope they are in stock (I would not be surprised to see a number of people selling locally purchased readers on eBay, at outrageous prices, since Amazon's stock of them has started to dry up).
The following are all in-stock (for now) and can be delivered immediate:
- Kindle (non-touch; no keyboard)
- Kindle Keyboard 3G
- Kindle Fire
- Kindle Fire HD
As the holidays get closer, I expect we'll see longer delays, even in the models that are now easy to get.
