will ship to Canada. She sells aroma chemicals in small (affordable!) quantities, which is nice for people like me who don't really know what we're doing yet.
Her website also organizes the chemicals by odor family and gives some hints on which of them are so strong that they really need to be diluted down a lot, similarly helpful for beginners.
