Extremely affordable! I keep one of these in each bad I have and even a few at my desk at work. It comes in tiny bottles of 60ml's with an extra 10mls for free! The price has gone up though probably because of excellent sales just from me LOL
Clicks also sells the larger pump action bottles which I feel is even cheaper to just refill the tiny bottles you already have.

My favourite is the blue bottle Happy Hands Come clean! This does not leave your hands dry like most hand sanitisers. And they fragrance lingers on your hands too! Perfect!
