Perhaps ten years ago, I bought a few of those (or a very similar model) at a Dollar Tree store where they were in fact $1 each. I think it was the one seen here:

Of course, now days Dollar Tree sells stuff for $1.25.

I love how the Ocean State Job Lot has scattered the trig functions around the keyboard randomly.
