It's not available from Amazon.ca, and it will take awhile to save up for that. It's unfortunate I live on a different planet than you. I don't have any of the seasons yet, but I do have two of the movies.
Edit---
Found it for $158 (Price with tax), at Best Buy. It would probably be cheaper ordering for the USA.
