That was the reason I bought a lot of stuff at their competitor baby-dump.nl. Until BP bought BD, and instituted the same policy there...

It's their site, they can do what they want. And as long as there's competition I can even admire them for making a sacrifice for something they believe in.

This kind of stuff becomes a problem when it starts arguing that others must do this too. If someone argues that all shops must be closed because their religion forbids working on that day, then that's an issue. But as far as I know, the Baby Park people haven't done that. They made a personal moral choice and sacrifice. Good for them.
