A quick money-saving tip for the kitchen (it's only pennies, but everything counts!):
When you seemingly can't squeeze anymore hand dishwashing soap out of the bottle, add water to the container and shake. You'll have a full bottle of less-than-full-strength soap, but it'll still be effective enough to get your plates and glasses clean.
While on the subject of dish soap, it would be great if more of us used plant-based liquids rather than the harsh petroleum-based soaps that contain phosphates, dyes and fragrances, superfluous ingredients that do nothing to improve cleaning but are quite effective at harming our health and/or the environment.
Many brands (Seventh Generation, Method, Martha Stewart Clean, etc.) exist and are available at stores such as Home Depot, Wal-Mart and Target, where they are priced competitively with the better-known national brands.
