I'm confused

I've lost count of how many times I've said that anyone can be a copywriter because everyone has a keyboard.

And this simple message from Woolworths is proof of this.

Does it mean that single-use plastic bags will be free from 20th June?

Or does it mean that Woolworths supermarkets will no longer be providing single-use plastic bags from 20th June?

Of course I know the answer. But will a busy shopper with a trolley full of goods?
