Been using reusable bags for some years now, even though there is no visible surcharge for plastic bags. And I get deliveries with biodegradable pellets in them. Just soak them in water and they dissolve!

Gyro remembered when he was young in England that everybody used calico bags and such. He used to work for the co-op and do deliveries on his bicycle! I guess a lot of things would still have been in paper bags, then.
