I was shocked when my PCP told me I could pick up a Duoderm in the bandaid aisle. I could have slapped a piece on as soon as the skin started thinning out and saved myself a lot of trouble.
They're pretty darn expensive for bandaids now, but the way the floor managers behaved you would have thought they were made of gold back in the day.
I didn't know about the Tegaderms... also surprising.

Making these things OTC is good news for pts. It will save a lot of dough on visiting RNs and MD visits.
