This week, regional average prices increased in all five regions. The regional price average increases ranged from just over 4 cents in the East Coast region to more than 13 cents in the Midwest region.
Three of the five regions averaged lower prices than in the same period last year. The East Coast region had the most significant difference, 11.1 cents lower than this time last year.
