For those of you that do shopping on Amazon.com, Bret over at frozenwarrior has put together a nice little tool that can save you some money. Amazon policy is that if the price of an item drops during the 30 day period after you purchase it, you can claim a refund for the difference. The problem is, who has the time to monitor the prices of the items once they are purchased? That’s where this little tool comes into play.

Called the Amazon Price Watch, it monitors the items you purchased for 30 days after you have made the purchase from Amazon. You simply enter the ISBN number (for books) or the ASIN number (for all other items) and you will automatically be emailed if the price of the product you purchased decreases in price.

The service is also helpful for those who want to purchase a certain item, but want to wait until it goes on sale or is marked as a clearance item.
