While the Kindle 9.7" DX EReader seems to have been dropped
... the last noticed pricing was $199.
Checking out the situation, I saw that, in the side box, they were announcing 9 used DX's available at only $9,999.00 each and then shown on the "Used" page:
While pondering the effect of sudden scarcity, I saw that the box at the right of the product page has been changed to a more doable lowest price of $149, although the "Used" page itself had not been changed yet for 8 of the 9 devices, so I made a screenshot to show you how much you will have saved overnight if interested in a used, large eReader.
However, I don't see the device in the Certified Refurbished, or Kindle Outlet Store page, although the $9,999 used-devices were listed as being shipped by Amazon.
Hopefully, by the time you read this, that page's data will have been adjusted -- but I couldn't resist.
(Some may still like that this is a 3G eReader that has free but very slow 3G web browsing on it, not available on newer Kindles.)
