At Adorama we do appreciate that our closing times can be inconvenient to some of our potential customers.
As others have noted, Adorama's owner is an observant orthodox Jewish gentleman, whose beliefs prohibit him - his family and his business - from operating on the Sabbath and on many of the religious holidays (which all begin an hour prior to sunset the evening before the day of the holiday, which is why we close early on Fridays).
We can't employ non-Jews here during those days, because to do so would involve the company conducting business - which is forbidden in Jewish Law.
Most holidays are actually only one or two days; two are week-long holidays. We do try to minimize inconvenience to our customers, by publicizing our closing dates well in advance.
After the holiday(s) end(s), we do reopen our sales and shipping departments as soon as possible in order to deal with the inevitable backlog of orders.
We would also take on add additional staff in the customer service, sales and shipping departments if necessary to help reduce backlogs and speed up the service to our customers.
In this era of 24-hour commerce which seems to take for granted that we all sleep with our i-phones under our pillows and work a relentless 60 or 70 hours a week, this is a special time for us to be with family and friends.
I guess it's unusual to find that there really are still people who consider their spiritual duty to be more important than making an honest buck out of our customers at every opportunity. I receive frequent emails from customers who state that in this day and age it is comforting to know there are people around who do not place money before all else.
Many businesses in the US and elsewhere in the world force employees to work on holidays when the time is better spent with their friends and families - or just relaxing by themselves
We are grateful for the understanding of our customers that this is an important element of our owner's value system. Perhaps the following links to articles in the Washington Post & the New York Times will help to make some sense of our closure policies:
We only have an extended closure periods twice a year - not for Easter & Xmas! - but for Sukkot (September/Ostober) and Passover (March/April).
We close on Saturdays but are open on Sundays - and all our opening / closing times are posted on our website.
I hope this helps; BTW I'm only an email away for advice and / or after-sales support with any order from Adorama Camera.
