Before the stickers we used a "rotary" with blue ink:

Changing prices was a real pain - we stole a can of hair spray and used it to dissolve and then wipe off the old price.

Did you have to use an ink pad, or was the ink somehow integrated into the device?

The price guns I remember were all metal, like the rotary stamp you posted. All I could find on the Internet were plastic models, and even they looked like antiques. I keep forgetting I’m that old.

When I worked at a supermarket chain in the late 1970s, they were moving away from those price stampers to label guns that shot out stickers. It was considered high tech at the time and if the price changed, you just put the new one on top of the old.

It was a big responsibility to price product in those days. You had to be a full-timer out of high school to even qualify to have one of those pricing guns and they had to be checked out and checked back in every shift. If you were issued one and let it out of your sight for even a minute, you were fired. Anybody else who even touched one was immediately fired.

Still a few years away from bar codes - that changed everything.
