Thanks for checking into that. I live in a remote area (the only US border I'm close to is Alaska!) so UPS usually charges a ton and, as others have mentioned, can be a hassle with the border.
I do like the sound of this kit as I'm looking to try C-41 at home for the first time and I like the idea of an all-liquid kit. Maybe if there are enough people in Canada interested we can figure out some kind of group thing to reduce border fees.
