AmazonWatcher alerts you of price changes on Amazon products, so you can get hold of holiday deals or be alerted of price falls on products you bought.
The application supports the six international Amazon sites and you can search for items by entering their URL, ISBN or ASIN. A preview image of the product, title and price will appear in AmazonWatcher's interface and the item will be added in your list. You can then choose whether to be alert by a sound, a pop up or by mail and manually set a price from which you want to be notified. The sound alert is horrendous though and it can only be set in seconds and minutes.
AmazonWatcher allows you to automatically place orders, for which you'll naturally need to have an Amazon account setup with your credit card details and 1-Click setup. We were a bit surprised to see items we hadn't picked appear in our lists. When selecting Amazon US, a Wii had already been selected (a trick to incite me to buy? who knows).
Despite a few limitations, AmazonWatcher can be a useful tool if you're the kind of person that likes to pounce on deals.
