I suppose I could run around to all the 'get this for a dollar' stores (with thier 5-10 ct pkg) and MAYBE break even with the cost. But it is much more convienient to grab one package of 100 ct or 200 ct and be done with it.
Our genealogist files obituaries at the Waushara County Historical Society museum. We use these as well as the old "sticky pages" for filing obituaries in loose-leaf notebooks.
I have made several informative notebooks of fossils and mineralliterature using the sheets as a protector of the articles within. The notebooks I have donated to several different schools along with the exact fossil and mineral specimens The students can read about each specimen in a well protected plastic sheet that will last for many years. Excellent product I highly recommend it.
