This can't be an original idea but here goes. Instead of a dis-incentive scheme for plastic bags we should try an incentive scheme. No charge for the plastic bag but a discount or refund for using your own bags.

Haven't seen anyone else use a green bag at the supermarkets in Broome for weeks if not months and we're on the lookout. How about a refund from Coles and Woolworths for the bags we don't use? Let the plastic bag users pay more for their groceries so that we don't have to pay for something we don't want.

Might help others to bring those bags from home.
