One example is B&H Photo - http://www.bhphotovideo.com/ On the footer of their pages it says: "Please note that B&H does not process web orders from Friday evening to Saturday evening." I would assume that in the sect of Judaism the owners belong to letting your site take orders constitutes work.
Another example is my Girlfriend - she closes her Etsy shop when she goes on vacation because she'd rather not take orders and have customers wait for her to return for them to be fulfilled.
I live in the Brooklyn Hasidic neighborhood. A couple weeks ago, one of the gentlemen flagged me down on a Friday night. He needed me, a complete stranger, to come into his home at 11pm, go down to the basement, and push the "open" button on his dryer so his wife could retrieve clean towels for their (many) children.
Operating a machine of any kind, to the extent of pushing a button, constitutes work in their culture. There’s a whole wikipedia page about the ongoing controversy over whether it’s okay to use light switches during Shabbat or not. https://en.wikipedia.org/wiki/Electricity_on_Shabbat
(they thanked me with a slice of cake, which was nice)
There's the whole Shabbat Technology industry - finding Kosher ways of using modern conveniences in accordance with the Sabbath laws.[1] For example, these folks make a bunch of devices: http://www.zomet.org.il/eng/

As I recall they sold out of bullshit rather quickly. Obviously these are just two variations of public relations, and as they say, if you can get people talking about your brand, that's good publicity. I still think it's a great idea to give people the day off. It's a business, why would we demand they go out of their way to turn away (on-line) customers too?
Am I the only one disturbed by the fact thats not all one mountain image that we are scaling down as we scroll? its just one photo after the next and the falling into the white void with CEO letter.
NITTY!
