Just a simple thing- but it stretches out our soap supplies. I love the foaming soap dispensers- to refill just fill at least halfway with water, even up to 3/4 with water and the rest soap. It's amazing they charge so much for those little dispensers and all it is is watered down soap. So, put them to good use and never have to buy foaming soap again! This also works well for shower gel, too, and smells so good. I am doing that with the excess supply of shower gel that I have, as I really use bar soap in the shower. So I haven't bought gel soap now in, over 2 years, and we never run out!
