a singular advertisement

It nice of the writer of this sign to set a puzzle to entertain us as we shop.

If it's about one umbrella, we're left wondering what the umbrella possesses.

Perhaps the umbrella's handle was $19.99. Or maybe its spokes.

On the other hand, if there's a 'typo' and the sign is advertising umbrellas, we're left wondering what other single item used to be $19.99 and is now $9.99.

What a mystery.

Using punctuation to mislead

When a new pharmacy opened in my local shopping centre, I was interested to see the sign saying it was Australia's Cheapest Chemist.

But wait a minute...

There's some tiny print on the sign - Is this?

So, the sign might say, 'Is this Australia's cheapest chemist?'

Horrible punctuation, though - 'Is this? Australia's cheapest chemist.'

Who knows? I'm not going to find out, because I think a shop that indulges in such deplorable punctuation is best avoided.
