Comparison Shopping

The website Pricenoia will compare the price of a book on all of the international Amazon.com sites where it is sold. It also lists the shipping from that country in US dollars, so you have a perfect comparison of how much it will cost. Many books, especially textbooks, are less expensive to buy in another country and have shipped to the US. (I mention this in the book.) Pay attention, college students!

Here is an example. The book "Elementary Differential Equations with Boundary Value Problems, Fifth Edition" costs $103.20 in the US, including free shipping. You can get the same book from Amazon.co.uk (England) for $45 plus $12 for shipping, making the grand total only $57.24- almost half price!
