I've had nothing but great experiences with Amazon. If you are a prime member, two day shipping is free, one day is $3.99 per item. If you have an Amazon visa card, you get 3% credit for Amazon purchases. My only caveat with Amazon is that if you have to involve them in a refund for a 3rd party purchase, you are limited to doing this only 5 times in your lifetime.
Recently I purchased some mats from Adorama through Amazon and somehow they were folded 3 times between Adorama and my house! Adorama gave me a full refund the next day after contacting them including the shipping costs too, so good for Adorama.
Finally, even though I'm not Jewish, I find it neat that companies adhere to their religious beliefs like B&H and Adorama too and shut down for a while. I believe that only B&H stop taking web orders during this time. I support this and can plan my purchases around this schedule. In my opinion, it's good for their employees and families.
Lastly, I have found a good local vendor - Denver Pro Photo and purchase from them too. It would be a sad day when there are no local photo shops where you can look and try different equipment. If I take their time to give me advice and guidance, I'll purchase it there rather then go and buy it from Amazon, B&H or Adorama.
