I bought a couple sheets of plywood and a nice new 10" saw blade at the
BORG, and maybe another $5 item. When the clerk scanned the cart, I guess

I didn't pay attention until I was pushing the cart out the door, and
glanced at my receipt.

Would you have gone back and informed them of the mistake?

Yes, of course.
