For those of you (us) that buy books online, there’s a new, free online tool for comparing prices between online shops: BooksPrice.com. The site also works for DVDs, music, and video games.
When you choose the book for which you want to compare prices, you’re shown either a table or a chart, listing stores and prices from lowest to most expensive, including the cost of shipping. You can choose your currency and general shipping info (i.e., your country) in order to filter your results. Amazon.ca seems to be the only “Canadian” store listed (as far as I’ve seen).
