Since I see this question get asked on here quite a bit, I thought I'd share my find. I've discovered a new source for Atomizers that I haven't seen mentioned on here. Not sure about other countries, but we have a store in the US for cosmetology supplies call Sally's that is open to the public.

I purchased two small atomizers there yesterday for <$2 with my wife's professional license. They would have been just over $2 without it, which is still a steal.

I now have my CK Eternity from a mini splash bottle that I never used, in a convenient spray that I will use more often.
