Here in NZ we are paying around $2.10/L. We don't have the weekday fluctuation that you have over there. But different stations can cost more. I always fill up in my little town because the next town over where the shops/kindy etc are is a tourist town and they charge about 10c/l more over the winter.

It costs DH about $100 per week to go to work and I pay around $50 per week for the kindy drop offs and pick ups.
