I've always hated wasting shampoo and the last part of the bottle that I don't have time to fight with in the mornings while getting ready for work. So I bought a pretty basket and set it on the floor next to the shower, now when the bottle gets too low I put it in the basket upside down. Then I use it up when I have more time and need to clean things like my trash cans, dust pans, etc. I use all the shampoo, get my items clean, and don't have to use up the heavy duty cleanser for those items either.
