amazon.ca & two listings

[Erman_94]

hey guys, im looking to get some blu-rays from amazon.ca...but it seems like a lot of the ones i search, i get two results (one cheaper, one more expensive)

for example:

http://www.amazon.ca/WWE-Wrestlemania-XXIV-Blu-ray/dp/B0017LIDPK/ref=sr_1_3?ie=UTF8&s=dvd&qid=1258821702&sr=8-3

http://www.amazon.ca/WWE-Wrestlemania-24-Blu-ray/dp/B00140KWLM/ref=sr_1_4?ie=UTF8&s=dvd&qid=1258821702&sr=8-4

they have the same thing for wrestlemania 25 (two versions, one is $10 more)

why is this? they are both 2 disc sets (shown by the picture) is the cheaper one a canadian release with french writing? and the more expensive an american release?


any help is appreciated,

thanks
