Thanks eSPhotos, that clears that up I think. It looks like they want out the door in any quantity.
sunsesame, bulk loading is a subject much talked about right here. Try Googling ('bulk loading' site://apug.org) and you will get a hundred hits. As for 36 exp rolls I doubt you will find them as the target market is (was) speed cameras and the 45m rolls are considered small for that purpose.
You don't actually need a loader as you can do it in the dark but I would caution a tyro against that if it's the first time.
