&gt;It’s kind of weird that he needs her permission for such a minor purchase

400+ euros isn't a minor purchase. At that price point I tend to get my wife's agreement too before I buy something (and vice versa).

For someone whose income is "well above middle class" as described by OP, it's certainly not a major purchase. 

Even as part of a married couple, I am still an individual who can make my own decisions and spend my own money. You don't have any money of your own that you can do whatever you want with? I am a strong advocate of joint bank accounts for shared expenses and future goals, plus individual bank accounts exactly for things like this.
