For those of you that live in Canada you can get Arista and Tetenal chemicals from Beau Photo in Vancouver (www.beauphoto.com). This was from an email with them in Dec 2012:

Tetenal E6 1L $69.70
Tetenal E6 5L $113.96
Tetenal C-41 1L $46.51
Tetenal C-41 5L $78.13
Arista E6 1 QT $44.29
Arista C-41 QT $53.78

All prices in CAD.

They started offering these kits as of October 2012. That's great news for Canada considering the options prior to this were pretty non-existent here. I still buy my Tetenal E6 5L kits from Germany at www.fotoimpex.de/shopen/. It's still cheaper even with shipping. However I will buy my Tetenal C41 5L kits from Beau Photo from now on since those are cheaper than Germany.
