Foaming Hand Soap Savings

My kids love the foaming hand soaps; however, rather than buying a new pump every time the old one empties, I save the old pump, buy a large hand soap refill (Wal-Mart for under $4), put approximately 1-inch in the bottom of the old pump, fill the rest with water, gently mix, and voila! you have new foaming hand soap. A large bottle refill will sometimes last us 8 months or more.
