A 4% Discount on Mankiw's Principles of Economics...

... is now available to book buyers in the UK! Thanks to a recent surge in the value of the UK pound with respect to the US dollar, United Kingdom book buyers have the opportunity to snatch up Greg Mankiw's 4th edition of his Principles of Economics text at a discount if they buy through Amazon.com's US storefront rather than through Amazon.com.uk!

Here's the screenshot of the US version from this morning (click for a larger image):

And here's the screenshot of the UK version:

Using this morning's exchange rate of 1 US dollar = 0.508 UK pounds, our preferred currency conversion tool reveals that the US-sold version of the text at 141.98 US dollars is now selling for 72.11 UK pounds - a 4% discount over the basic selling price of 75 UK pounds! And the deals only get better if the pound continues to rise against the dollar (and also if Amazon.com.uk doesn't catch on and begin discounting its version to eliminate sales losses from arbitrage!)

Compared to the New Economist's recent survey of the relative costs of Economics books on Amazon in both the UK and US, Mankiw's book provides a rare discount for UK economics book buyers, as the deals normally work the other way around!

Who knew that you could use an economics textbook to learn something about prices, currency exchange rates, arbitrage and international trade?
