I have a pack of 5 bags which I purchased from Coles years ago. I carry them in my handbag. Over the years I have made a few but the material is expensive. All are washable and I am never without them.
There used to be a delivery service at Coles where you could go shopping as normal, picking out your items and paying for them at a register. Pay $2 more and have them delivered.
My Mum didn't drive and had 6 kids to buy for.
