Actually Amazon has put a price slash on the Kindle 2 just before Christmas, and it is now selling $100 cheaper than the price I got my Kindle, and it adds in international wireless access and native PDF support… So it should be selling at the best price already:

If you don’t need to have international wireless function, you can get refurbished version at the bottom of the offer list here. It works exactly the same as new Kindle, just it only has free wireless within the United States and not other countries:

Hope it helps
