I always packed my lunch a few times a week, but after reading MMM, I've started packing it every day, including weekends. I can make a decent lunch including fruit for about £0.50, whereas food from the supermarket might cost £3-5. Plus, I've been vegetarian for about 16 years now.
I only use public transportation, and today I took buses and trains to get to work, then to a social event.
I rarely shop for new clothes, beauty products and gadgets - this is an important one that is sometimes overlooked. In the weeks leading up to Christmas I've been given enough lotions, creams and body wash to last for the entire year or longer. Strangely, I've also been given jeans, a summer dress and converse, which have been sitting unused in someone's closet. Makes me think that we should do 'closet trade' type events more often, instead of buying new!
