Besides selling it directly, Amazon has also removed third-party reseller listings and even new and used devices sold by Amazon users through the marketplace.
Taking it one step further, if you search for the items you will instead get a recommendation for the Amazon Fire TV or the Amazon Fire TV stick.
As part of their decision to stop selling the items, Amazon says "It's important that the streaming media players we sell interact well with Prime Video in order to avoid customer confusion." This, of course, doesn't make too much sense since Chromecast's SDK is open and Amazon could have added support pretty easily.
