The Canadian Amazon website (Amazon.ca) isn't any different than the European one. Both sites just have the 360 version up, although the EU one is the regular version while the Canadian one is the Collector's Edition. Very weird.
A question to the community reps if they're reading this thread (Or any other Canadian who might have made an attempt)... Are Canadians able to purchase and download the expansion from the SE store? Because the American Amazon website (Amazon.com) is no good and only works for US buyers for some wacky reason, so if Amazon is no good the SE store is pretty much my only hope.
