The authors of a forthcoming Economics Letters article (pdf) gathered data from Amazon’s American, British, and Canadian web sites to demonstrate international price discrimination. According to the authors, Americans pay significantly more for textbooks on average. They offer a number of demand-side hypotheses but do not test them.
I’ve found a number of cases where American customers can save money by purchasing their textbooks from amazon.co.uk and paying for international shipping (£6.98) rather than using amazon.com. Check it out:
