What my friend, Sarah, was really curious about is how we manage groceries. My first response was I make all of our condiments: mayo, mustard, ketchup, horseradish, etc. I make our bread (4 loaves every couple weeks), I make Kombucha, Yogurt, I buy in bulk, I buy things that are on sale unless it's a favorite brand we can't compromise. We still buy just about everything organic and we still only spend about $85 bi-weekly. As all of the effort stated above is beneficial to our grocery bill what has the largest impact is WE USE WHAT WE ALREADY HAVE TO MAKE FOOD!! The pantry items get used, freezer food gets used, perishable items get used BEFORE we replenish or buy more.
We also belong to a Dairy CSA, Veggie CSA, and Meat CSA. Our dollars here go directly to the food produce and we get a TON of food for our dollar.
AND, everything is so easy to do and takes minutes besides the mayo which is a little more time consuming.
