How to Find the Cheapest Everything

With so many shops making their product prices online, it has become increasingly easy to create some interesting comparisons. There are websites that help you to compare prices for books and DVDs (even calculating the shipping for you) such as Booko (usually you'll find BookDepository is the cheapest). There are many similar websites such as Webjet and Adioso which help you to compare air ticket prices. For electronics, there's StaticIce and Shopbot. 

But the most interesting websites are those that help you spot a bargain the moment a shop changes their price. Mildsurprise is one of those websites which allow you to see what are the biggest discounted items in the last 24 hours, week, fortnight or even the past year. You can sort the list by price drop or percentage drop. You can even look up a particular item and see how the prices have fluctuated in various stores (and which stores have actually increased their price!)

Then there is the price watcher for Amazon, an interestingly named website called CamelCamelCamel which helps you track the price history of any product on Amazon. Do you know of other useful comparison websites that you love exploring? Let us know.
