It definately doesnt hurt to try or even ask. In fact if you really want to know how my conversation went exactly when I did it was this...
CSR: "Hello, how may I help you today?"
ME: "I was hoping to cancel my order, because I rather not wait and just head to the Apple store and pick it up"
CSR: "Sure, may I have your order number please?"
Me: "(blah blah blah)"
CSR: "Mmm, yes we can cancel it if you like..."
Me: "Is it possible you can give me a discount if I kept my order?"
CSR: "Umm, let me see what I can do..."
*waits about a minute while I hear him typing away*
CSR: "I can give you $50 dollars off if you keep with your order?"
Me: "Thats it? Nothing else? Uhh.."
CSR: "Well, let me see what else I can do" *waits another minute* "I can take off $60 dollars and bump your shipping to 2 day shipping."
Me: "OK!!!"
So yes, I actually asked them if they can do anything for me. I felt that he was simply going to just cancel it which is why I asked. If he said no, I would have just waited till my local Apple store had some in stock. So just try it, it wont hurt, you can only benefit from trying
