I clean a lot with a mix of vinegar/water/dish soap. Works for cleaning counter tops, sinks, mirrors, you name it. I use sheets of newspaper instead of paper towels to clean the mirrors and windows (on the rare, rare occasion that I clean the windows).
I look for the cheap cuts of meat, freeze them, and then figure out how to cook them if it's not a cut I'm familiar with.
I don't go cheap on shoes - I like good shoes, my feet are picky. I like good sweaters, too, cotton or wool, and I'll spend the money for them.
I haven't bought new jeans in probably five years, get all mine secondhand (and most as good as new). I let my husband cut my son's hair, and I cut my daughter's bangs.
