Just read that Woolworths is planning to trial paper bags which will be more expensive than it's plastic bag (20 cents vs 15 cents).
The article also mentions the "bag for good" which will be replaced it it's damaged no matter when it was purchased. Since it's been more than six months since this deal, I thought I'd repost it as a OzReminder.
We’ve launched a new reusable bag in our stores called the Bag for good™. It’s yours to use again and again, and if it ever gets damaged, we’ll replace it for free no matter when you bought it from us. Simply bring your damaged bag to the Customer Service desk in any of our stores and we’ll swap it for a new one. We’ll even recycle your old one so it can keep doing good.
