When I pre-ordered from BHPhoto on March 2nd the availability of the product was Backordered. That was before it showed up as Pre-Order. So I did e-mail BHPhoto to asked them what the difference was and they said...
"Thank you for contacting the Customer Service Department at B&H Photo Video and Pro Audio.
They both mean the same thing, but it comes down to the same conclusion - we don't have it yet.
Pre-order means that the item is on Backorder, and is available to be pre-ordered as this is a new item that wasn't released yet, rather than just Backorder which may mean that we just ran out of stock."
This past saturday I received an e-mail telling me that my Backordered product (5d Mark III) is still in Backordered status. duh! lol
I also e-mailed them asking them if they know when they're going to ship these out and how much it'd cost me to change the shipping method to Overnight and the response I got was...
"I sincerely apologize, but Canon has not advised anybody of the shipping date yet. It will cost $65.25 to have the package shipped over night. With the free shipping that you have now, it will take 3 days. "
Bottom line...gotta wait patiently.
