I ordered a 21.5" iMac together with the Apple Keyboard with Numeric Pad thinking that it is Wireless as well. However, I just found out that it is not! and I would like to change the Keyboard with Numeric Pad to the Wireless ones. Anybody has experience changing the order when the Status is still "Processing Item"? Is it possible to change now? Or do I have to wait for the items to be shipped and then send back the Keyboard with Numeric Pad for the Wireless one. Thanks for your advice.
