I go through phases where I stock my pantry and freezer to the max. Sometimes it's because there are great sales, other times it's because we have a little extra money and I like looking at a full pantry.
My tip for today is to shop from your pantry and freezer this week instead of going to the grocery store. Chances are that you can create a week's worth of meals from the things you have on hand. It will stretch your creativity as well!
If you're like me, you'll still have to go to the store to buy milk (we go through 2-3 gallons/week!) and bread -- but don't buy anything else! You could take the money you've saved and put it away for the upcoming holidays.
