Not cheap but it's a start.
Finally Lost ... Wait what? Only season 5
Actually, it's cheaper than the US. While we don't have the option of buying the Standard Def shows @ $1.99 we get the HD shows at CAD$2.45. The US HD shows are US$2.99 which works out to CAD$3.40ish. Canada's HD shows are cheaper by almost a dollar.
I think the more interesting story here is the addition of US studios. NBC Universal, Fox Studio Classic, ABC Studios, etc.
Pretty much all the American network shows are on here now. Or at least the good ones worth watching.
In other words, 30 Rock.
