It wasn't time for a shopping trip yet, but yesterday I ran out of coffee filters. And at our place, coffee in the AM is Not Optional. :) My SO suggested a paper towel, but I've been down that road before, and what usually happened was the towel collapsed and grounds got all over. So I carefully lifted out the used filter, dumped the grounds out of it, and washed it in clear water (you have to use a delicate touch here). I hung it to dry on my washcloth rack and reused it. No problem--the filter held up fine, the coffee tastes normal, and I may do this on a regular basis to save money. Another food-related tip is to not only serve smaller portions, but to put them in smaller bowls, cups, glasses and plates. I use salad plates for most meals, because a heaping plateful is a heaping plateful visually but costs less if you use a smaller plate. (Satiation is partly psychological, you know...portion creep.*) This is usually aimed at dieters but it saves you money also. *Just as a forinstance, look at the change in the size of Coke bottles over the years. I have a four-ounce glass that I use to drink soda from, and even the tiniest modern bottles fill it three times over.
