For a while the buyer had a deal to get grey market Kodak Limited Film from the UK as it was cheaper than the film from Kodak Canada. That suddenly stopped after a visit from the Kodak Canada rep. I only bought a few rolls of the UK stuff but they were still re-loadable when the Canadian and US ones were crimped.
Funny thing was we could send a roll of slide film (AnscoChrome, or E6 ) out before the pickup at 4 Pm and it would be returned by the 4 pm Pickup the next day. (lab sent someone to swap the pickup bag every day)
Of course working with Cameras all doy the last thing I wanted to do on my day off was to even think about taking pictures.
