I’ve converted to reusable bags but I’ve noticed on my last few trips to the supermarket that about two thirds of the shoppers are buying the plastic 15c bags for all their groceries.
You can also buy the old plastic bags from a few suppliers. One wholesaler in Queensland sells them in various sizes and packages, one of which is a box of 2000 large size bags for $51 and $10 delivery.
