Gardening. I grow a lot of tomatoes, boil for one minute, peel the skin, smash and may put in garlic salt, fresh basil or whatever and freeze in freezer bags to use in spagh"etti, chili, or soup. I freeze shredded zucchini for muffins/bread. I just tried spaghetti squash and love it but won't pay $6 for one when I can grow it for 30 cents. The best part is, my 5 year old grandson is eating squash, eggplant and other things just because he helped grow it. Oh green beans also. In the earlier months I grew red lettuce for the first time and had fresh salad every day.
I clean with bleach and comet type only as my bf has a chemical allergy. I have never found one of those "this beats all cleaner"--that costs $5.98 to beat a little comet, baking soda or bleach.
I love yard sales and second hand stores. I have much more fun finding a good buy then shopping in a store where there are 20 of the same kind. I use to find new Levi's for $1 sometimes. When my kids got to the teen years and refused to wear secondhand clothes, I came home, washed them, hid them in the back of their drawer and someday said....oh look, you must have forgotten about these.
I price insurance every 6 months during renewal time. I just saved $30 a month changing (both major insurance companies).
