Buy a stash. Down here I can find them at health food stores, Publix and Exkerds. Online I've found them at www.earthbaby.com. THEY ARE THE BEST.
Hylands.com can also give you local stores. I also encourage the Hylands Kids Kit and a good book about Homeopathy. We've had lots of luck for all kinds of things with the kit.
Badger's also gives local stores on their site, but I just checked and I don't think there are any near you, as far as I can tell: http://www.badgerbalm.com/i_stores.html#canada
But if you're looking to save on shipping, you may be able to call one of the Canadian outlets listed on that site and see if they'll ship to you? Just a thought. I don't know if they would even do that.
