If you shop at Amazon.com (a lot) wouldn't it be nice to know when there's a price drop on that special item you need or want?
There is a Firefox add-on called Price Drop that gives the user the option to track prices for selected items at the Amazon.com online store and notify him/her when the price drops. In addition to keeping track of price drops at the Amazon store it also notifies you if the price dropped after purchasing an item which helps in getting a refund for the item you bought because of the lower price.
The extension adds a ‘Price Drop. Track this item’ row on every single product page at Amazon. Clicking the row adds that item to the list of items that are watched for price drops. The list of tracked products can be viewed at anytime by opening it in Tools > PriceDrop and it is possible to delete items in that list as well.
The user will be notified in a popup window if a price drop has been recognized. A link to the product page at Amazon is given in that popup as well. Unfortunately the old price is not mentioned in there, only the new price is mentioned - but any price drop is a good thing.
