Discounted Liquid Hand Soap

I discovered a way to refill liquid soap dispensers for 1/4 of the cost. In the past, I purchased liquid soap at $1 for 7.5 oz (sale price). By using bath soap for refilling the hand soap dispensers, I'm only paying $1.50 for 48 oz. This is 1/4 of the cost, and it seems to clean our hands just as well.
