Amazon Pre-Order Price Protection?

[dvdirv]

I placed a pre-order for Coraline which comes with Amazon's pre-order price protection.

My price was $20.49. Yet today (day before street date), Amazon shipped my order at the original price instead of the new price today which Amazon lowered to $19.49.

When I received my shipping notice, I noticed it had the higher price, so I contacted Amazon customer service for a $1 adjustment (it's the principle of the thing!). I could have re-ordered at the new price and send the original item back, but I was trying to keep things simple!

When I called them, they said they could not do an adjustment once the item is shipped. I thought the price protection was in place until actual street date, but not after since Amazon canceled it's 30-day post price protection policy.

Amazon did offer to make "an exception" and refund one dollar on my account. I even had to talk to a supervisor just to do that!

What is going on here?
