Issue a “Zero Spending Challenge” to your family to find ways to use what you already have and avoid any extra shopping trips as long as possible. This works very well for people who get paid once or twice per month.
Plan your meals around the items you already have in your pantry, get creative and find ways to use the stuff you threw in the back because you weren’t sure what to do with it. There are great websites like AllRecipes.com which have an ingredient search that helps you find recipes that use specific ingredients.
When you run out of cleaning supplies or disinfectant spray, mix up some home made using about a 50/50 solution of vinegar and water, or scour with salt and baking soda.
Find free activities you enjoy, such as take a walk to the park, visit the library, do a movie swap with friends.
