Average retail gasoline prices in Arizona have fallen 4.1 cents per gallon in the past week, averaging $1.91/g yesterday, according to GasBuddy's daily survey of 2,269 gas outlets in Arizona.

"The continued and unprecedented plunge in the price of crude oil has continued, allowing gasoline prices in virtually the entire U.S. to continue plummeting," said Patrick DeHaan, GasBuddy senior petroleum analyst. "From West Coast to East Coast, the decline has hit virtually everyone- and amazingly, we saw a gas price war yesterday in Houghton Lake, Michigan, where for a brief period of time GasBuddy confirmed stations selling at just 47 cents a gallon- prices unheard of in this century.
While the 99-cent per gallon barrier was breached there due to competition willing to lose money, the downward trend taking place across the country will continue, with the national average likely to fall into the $1.70's soon as motorists continue to enjoy falling fuel prices," DeHaan said.
