Amazon changes the prices on its products constantly - so how do you know when to buy??

Two websites track amazon.com price changes for free:

• Price Protectr: http://www.priceprotectr.com/
  
• Buy Later: http://www.buylatr.com/
  

Simply enter the URL or ISBN number (for books) or the ASIN number (for other items) and you will get an email if the price of the product you purchased decreases.

The price monitor is useful if you want to purchase a certain item on Amazon, but want to wait until it goes on sale! Prices can change multiple times a day on popular items around the holidays - so put your wish list into one of these websites and monitor for the lowest price!
