In post #23 dated 23. nov. I promised to return if there was something new.
This is unfortunately not the case. I can't buy an Oasis anywhere
In the meantime there have been several strange things happening on the various Amazon sites.
Amazon US said that the Oasis could be shipped to Denmark, but you also had to select your destination from a drop down box. Selecting Denmark would deactivate the "Buy Now" button

Now I can do "Buy now" but when it comes to specify an address I am redirected to UK.
For the time being Amazon UK and DE simply states that the device can't be shipped to Denmark.
It is fortunate that I have other ereaders.
