Amazon may be the biggest (and most popular) online retailer in North America, but its currently facing some pretty stiff competition — from Amazon Canada. The Canadian loonie seems to be stuck in a downward spiral. And while that's concerning for Canadian residents, who are dealing with much higher grocery costs and lower returns on savings and investments, consumers from the United States can take advantage of the exchange rates to get lower cost goods. Cheaper Blu-ray Box Sets One area where we've been seeing noticeable savings is Blu-ray box sets. Movie and TV box sets here in the US are some of the most expensive gifts, with one season of a show sometimes running from $60 to $80, depending on the show and where you shop. The difference in pricing on Amazon.com versus Amazon.ca is pretty significant in some cases. At times, the average savings between the two sites is about 20%, but in individual cases the pricing from Amazon's Canadian site can sometimes be closer to what we see here in the US around Black Friday. Many of the cheaper deals we found were still cheaper with shipping costs added. Of note: Both the US and Canada are in the same DVD region, and many Blu-rays are region-free anyway, so any Blu-ray purchases should work on your player. Still, it never hurts to check compatibility when buying discs from an international seller. Readers, will you be price-shopping on sites like Amazon Canada now?
