I think only one post seemed disrespectful, but kudos to the poster for clarifying that he simply did not understand the orthodox/hasidic jewish take on the sabbath. Even though "honor the sabbath" and the prohibition of working on the sabbath is common to Christians and jews, it's very rarely adhered to. Baptists and other Christians off course at one time kept Sundays pretty much reserved for church, hence the old "Blue Laws" that kept bars and shopping closed on Sundays.
Within the Jewish community, very few keep the Sabbath. The Orthodox and Hasidm take a very strict view. You can't work, you can't handle money or conduct business, drive a car or even turn on any electrical device(like elevator, TV, etc).. There are many "loopholes".. For example, in an Orthodox temple, non-Jewish employees might be employed to handle lighting, etc. Timers are often used on elevators, eg, you can ride in one, but can't operate it.
I give the guys at B&H a lot of credit for sticking with their beliefs. They probably lose some potential sales, not only on w/e's but on all the holidays they close. There are many holidays that most of us, including non-observant Jews such as myself, have never heard of. B&H and others probably could have found some rabbinical interpretation to say that internet sales were not really work, since presumably the website was not set up on the Sabbath and only the customers are pressing the keys. However they chose to obey what they see as their faith, and are still highly successful.
hope this gives some explanation,
