Is it possible to get a refund from amazon if the price drops after ordering?

I tried asking this question on amazon ask ville, but no one responded yet, amazon customer support will probably take at least 3 days to respond so in the mean time I though I would ask here.

Yesterday I ordered an item from Amazon, the price at the time was $24.99. The item was sold by amazon and not a 3rd party seller. A short time after completing the purchase, the price dropped to $19.99. As of now the item has not shipped, I don't like the idea of trying to cancel and re order because there's no guarantee that the order will cancel since it's already processing.

Essentially what I am trying to find out is, can I be reimbursed or credited in some way the difference in the price, because it changed almost immediately after the order was completed.
