Isn't this an interesting economy? It brings back memories of the 1970s!! I have retro-ed to some of the things I did to save money then and started using them today.
You've heard of things like make a grocery list and stick to it, etc. But my focus is making what I do buy s-t-r-e-t-c-h.
One tip...when using dryer sheets, use more than one load. I reuse them over and over until there is no product on the sheet itself. You can put more than one gently used dryer in with towels, etc.
Just because it's been thru the dryer one time doesn't mean it will not work in a second load, etc.
