I’m so spoiled. I try to ONLY buy the foaming hand soaps. Once upon a time I worked at Ulta and got to use my discount to buy it. Now, I’m VERY frugal and have to improvise every once in a while.
My mother actually taught me this trick.
Take your soap dispenser that makes the foaming soap and fill it up a third of the way with dish soap. Fill the rest up with water. And done! Super easy and super cheap!
