So it looks like onecall is out of stock on yesterday's batch. The page for the 24-70 is back up and the item is listed as 'Coming Soon'. Unfortunately it looks like the price went up to $2,500.
My PC Nation order also went from In stock to back order status as I was a new customer and apparently got shafted. Waiting to call as soon as they open this morning to see what is up.
Something similar happened when I ordered my 5D3 from onecall....item was in stock when the order was placed, but soon switched to 'backordered' in the order status. I called and they assured me that my item was in stock and it shipped later that day. I am hoping this is the same case with PC Nation, although it is probably just wishful thinking and my wait will continue.
EDIT:
Yup, spoke to customer service and they oversold on the lenses. I cancelled the order and put one in at Kenmore. I missed their ebay offering last night, which had a little bit cheaper shipping and the +-$45 ebay bucks.
