I promise this is the last grocery article for a little while… 

This tip really goes to the heart of economic theory and a concept called inelastic demand.  Which everyone seemed to know (except me at first) means that when there is an inelastic demand you will buy a product at any and all prices.  Most of us have an inelastic demand for gasoline, for example.

DH, is using one of my favorite techniques, the stock-n’-store method of frugality.  He knew that he would use more chicken broth in the future, and he saves $0.39 a can he will save $19.50 for as long as the case lasts.  These savings are long-term, you will be hurting right away (spending $25 instead of .50).

 Here are other things you can use this method on:

1. Other canned goods-  Soup is cheaper in the summer than in the winter.
2. Frozen Food - We have a big ol’ bag of french fries in the freezer just to prevent late-night trips to Mickey D’s.
3. Toilet Paper-  This stuff has substantial shelf life and most everyone uses it, we buy the softest available and we buy it in bulk.
4. Toothbrushes- My dad hasn’t bought a toothbrush for himself since the 1980’s, he gets extra free ones from his dentist.
5. Fresh Veggies- Garden produce can usually be frozen, or else turned into something and frozen.  Using extra tomatoes and making several gallons of tomato sauce saved us hundreds when I was growing up.  Yes there were lots of spaghetti and chili nights, but Dad fed himself and 3 teenage boys on $40 a week.
6. Fruit- Get some jam recipes, canning recipes, or big ol’ freezer bags.  Frozen fruit can still be turned into pie filling pretty easily (we usually go half fresh half frozen though).
7. Junk Food- Do you have any idea how long a Twinkie will last?  I hear it’s more than a few months.

Let me know what things you’ve stocked up on to save money.
