The other places, it seems, don't want to be bothered with the cross-border hazmat paperwork (I don't blame them, it's not their primary business).
Unfortunately, the Formulary-repackaged kit is not overly cost effective vs. local dev. only processing. The kit is US$28.95 plus US$35.75 for shipping (via USPS) to me here in Winnipeg. Assuming a capacity of 16 rolls x 36 exp (same listed capacity as the Unicolor kits), that's $4.04/36 exp. roll. Dev-only is $4-5 at most places I've checked.
I was about to go the powdered-kit route as well, but I've managed to hook up with a fellow Winnipegger who has repurposed some Konica mini-lab chems for home use. So, that might be one route if you're in TO.
