There is also a baby products online store in the Netherlands that for religious reasons is closed on Sunday. You can browse the site but you can't buy anything.

The page is in Dutch, it explains that they're closed because get believe Sunday is a day for rest: https://www.babypark.nl/zondag/info-bp.html

The biggest camera store in NYC, B&H Photo, similarly closes their website checkout on Saturdays and on all the major Jewish holidays. It's mildly inconvenient, but it has never really stopped me from ordering from them. I think maybe one time it made me order from a competitor.

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.

We have similar e-commerce sites in Israel that close on Saturdays for religious reasons.

As someone living in a relegious country with religious parties in parliament, I see this as a slippery slope.

It's a way for religious groups to normalize forcing their lifestyle on the rest of society.

Religious mandates always tend to expand: what starts as "I don't care if you close your site on Sunday" can quickly escalate to "Why are you telling my wife and daughter how they should dress in public?"

Beware

I happened to want to order something there last Sunday. While digging into it, I notice that their closure seemed to be implemented only on the frontend using JS. By disabling some scripts, I was able to add products to my cart, which normally isn't possible on Sundays.

In the end, I didn't proceed to place my order on Sunday. It felt a bit disrespectful, and it was already late. (So I ordered half an hour later, which was technically Monday.)

Same for the SGP, the Dutch fundamentalist Christian party: https://sgp.nl/

I share few of their values but I quite appreciate this one.

Honestly, I don’t mind it. Our lives are so commercialized as it is. If I can’t order a new stroller until Monday, I think I will survive.
