I have a friend that cleans houses for a living. She owns her own business. I recently went with her to buy her supplies. She goes to one company to purchase everything. Everything she buys is bought in bulk, because it is much cheaper that way. She buys cases of different cleaners, disposable gloves, rags, brushes, mop heads and other items. It is amazing how much she saves by buying them in large quantities at a time, instead of small amounts. She gets paid well for cleaning houses and buying her supplies this way makes her profit much higher.
