Gas prices are suddenly falling as oil prices plummet.  When 2017 began, analysts said gasoline might approach $3 a gallon by Memorial Day, but that was off.

Now the number of gas stations in the USA selling fuel for less than $2 a gallon has nearly doubled since last week to 5,177, according to GasBuddy.

Gas is cheaper in 49 of 50 states than it was last week.  Prices average $2.37 as of Monday afternoon, down about 6 cents from April and up about 11 cents from a year earlier.  Here's more from USA Today!
