Agree. A lot of this has to do with habits. If you know that plastic bags are 10 cents each then suddenly you quickly learn to always bring 10 reusable bags with you to save the money.
Mostly I have just gotten very good at balancing a surprising number of items on my body while walking out of the store.
(and I started long before we got a plastic bag fee, fresh bags rarely crossed my personal convenience/waste threshold and I still happily pay when they do)
