If you regularly browse Amazon US, you might have noticed that some Nintendo products sold directly by Amazon have seemingly disappeared from the online store. Now, Bloomberg has published a report on why that’s happened.

According to Bloomberg’s sources, the issue presented itself when Nintendo noticed that certain third-party sellers on Amazon were undercutting official products. They would essentially purchase the products in Southeast Asia, where they were presumably cheaper, and then sell them in the United States via Amazon.

In an attempt to reassure Nintendo, Amazon offered to attach labels to products to guarantee their authenticity. However, the proposal wasn’t deemed enough of an assurance to Nintendo, and the Japanese company ultimately decided to remove its products from Amazon in the US.

When Bloomberg asked Amazon for a comment prior to publishing the story, a spokesperson simply commented, “The claims made by Bloomberg regarding our relationship with Nintendo are inaccurate,” without providing any further details on the subject.

Whatever the case, the fact remains that the issue prevented Amazon from participating in the launch of the Nintendo Switch 2, which turned out to be the fastest-selling console in history with its over 3.5 million units sold in the first four days since the launch date (June 6), going twice as fast as the original Switch when considering the same timeframe.

What’s perhaps even more impressive is that even without selling directly on Amazon US, by far the biggest online store in the country, the Nintendo Switch 2 still sold 1.1 million units across the United States in the launch week, beating the record previously established by Sony’s PlayStation 2 in October 2000. By the way, Nintendo products (Switch 2 included) are regularly available in several countries, such as Japan itself, the United Kingdom and Canada. However, Amazon US makes up two-thirds of the store’s global sales.
