After reading the stories about the bad experience with Adorama, I decided to call them first to check the stock status of the items I want to order. The result was they wouldn't even let you finish your questions and hang up if they found you would not place an order immediately. I don't want to tell the stories here. But I do want to say ALWAYS CALL TO CHECK THE AVAILABILITY OF YOUR ITEMS BEFORE YOU PLACE AN ORDER!!! AND NEVER USE ADORAMA!!!
In contrast, B&H is better, although not much. But at least they did make the checking before answering your questions.
