You just don't want to run out of the stuff. Periodically you will see specials on it at FragranceX and other places - so grab one. I use other soaps and creams, but Tabac is clearly the best of them for my face.
I use my tabac stick regularly and have yet to see it's level drop. I have three refill sticks in the hoard closet, just in case it suddenly disappears.
After my C&E Sandalwood runs out, Tabac is the next on my list to try out. I've only made a little dent in the C&E and I know if I tell the wifey I want another soap before the current one is gone she might not like this hobby anymore. I'm getting impatient!
