Amazon uses cookies to track which site design you have seen last.

They are constantly redesigning their pages (I've seen up to 4 completely different versions of a page in use at the same time). They have to lock the design through cookies (otherwise you would be seeing a different design on every refresh).

No, I'm also in Germany, got the new site right away. Opened amazon.de in another tab to compare the changes made. Now we'll see how long it takes until amazon.de changes as well.

Not sure about this. I'm on the same network as my boyfriend. Yesterday he pointed out that amazon.com looked different. I'm on my laptop and it's not showing the new design.
