Okay, I just got this email from Amazon.com:

Now, it would be one thing if they were calling me on my history of purchasing lame, girly non-games, but it says right there that it's basing the suggestion entirely on the fact that I've "bought or rated"
Mario Kart DS and/or other Nintendo DS games. Seriously, what? Did everyone who has bought DS games from Amazon get this email? How is "Holly Hobbie and Friends" notably similar to Mario Kart in any way?
