The following Everyday Savings Tip comes from, Lori:
When the bottles of shampoo or bath wash become very close to empty, just put them in a cup on the edge of the tub till the next time you need it so it can drain down. If you don't want to wait you can take the top off and run your finger around the inside of the bottle. It's amazing how much gets stuck on the “lip” of the bottle.
Those last little drops are great for making bubble during bath time for the kids too!
