An organized kitchen is key to saving money on groceries. The less organized the kitchen, the more time is wasted looking for ingredients, finding substitutes, running to the neighbor's house to borrow or driving to the store to potentially pay more for the item in the long run.
Keep this list handy. When you get low or run out of something, cross it off the list or otherwise make a mark so you can plan for the next shopping trip, check sales and make plans on which stores to visit to save the most money. Keep these items on hand and you will always be ready for spur of the moment meals. Adjust can and bottles sizes and amounts according to your preferences.
Stock up on sale items! Realistially a 3 month supply of the basics is a good money saving goal. Most properly stored items can last for years regardless of sell by date. Items to buy in bulk for a more than 3 months supply include paper and chemical products such as toilet paper, paper towels, shampoos and soaps. You don't have to stock up for doom's day to save a few bucks.
