Many people reject thriftiness because it seems like too much work. Smoothing used aluminum foil, saving bits of string, carefully dispensing Charmin square by square...it's the stuff of which stereotypes are made. (I don't do those, myself, but apparently my mention of kitchen scrap cookies left a bad taste!)
The easy part is the art of observation. Just look! Look around as you go about your day. Look at bulletin boards in passing. That's how we found the no-cost art classes and museum visit. Notice the outdoor signs. Free Chick-Fil-A sandwich for parking in the rear of the YMCA? I'll take one! Read the fine print. Paying one bill electronically saves me a $2.50 paper charge each month. Gather all that junk mail in a basket for later. Flip through the ads as you have a nice long soak. This write-up features a bucket-style florist with half-price stems after 3 pm--wrapped in tissue and tied with a bow. I'll remember that next time I have to make an unexpected hospital visit.
You never know what you'll need to know later. Information is free. Grab it wherever you can!
