Was in the same boat. A WORD OF WARNING!!

iPad delivered by May 28th, camera connection kit 7th June. However if you read your order it says items will not ship until order is complete.
I rang Apple and they confirmed the order would not ship until all items available even though the iPad says delivered by 28th. The rep advised I cancelled the camera connection kit and now my order says delivered by 28th May.
I origanally asked about split shipping and a request was made but nothing came of it, order still said ships 7th Jane. After my second phone call I asked about this and rep said probably not going to work so better to buy camera kit at a later date.
