Ok, I went ahead and ordered. Six from Canada, TOE from US. With Amazon prime free shipping on TOE, and shipping but no tax to Canada, came to $140.43 total, or $20.06 each. With price guarantee, could go down but not up. Assuming delivery goes ok, I'm pretty darn happy.
Thanks to all that have contributed to this thread. If any kind of "super deal" comes along before the release date, please post it; hopefully I could still cancel, but really, I think this is going to be the way to go.
