You were correct - B&H had "all items to ship together" on the order. The H Mount Adapter G was holding up the order / everything else was in stock. I told them to drop the adapter and the agent said the order would ship tomorrow. Again, thanks for the tip.
I tried to do that, and it didn't work:
Agent: We can only release items that are currently in stock on an order to ship out and not wait for the backorder. At this point all the items are backordered so we are not able to release anything. I would suggest contacting us again to see if anything is in stock and if there is something in stock we should be able to release it to ship right away.
Me: Is my order set up for you to ship partials now?
Agent: No, we cannot set up an order to ship partial if everything is backordered.
Me: If the body comes in, will you hold it for me and not let someone else whose order came in after mine get it?
Agent: Correct, it would be held for you.
Me: OK. Will I be notified?
Agent: I do not believe that the system would notify you. I would suggest contacting us again in a week or so and we may have information as to when it will be in stock.
