It's a gift for Christmas travelers; gas prices at the pump continue to drop.

The national average for a gallon of gas is $2.43, according to the Lundberg Survey.

That's down eight cents from two weeks ago. Gas prices have been falling for months and are down more than 54 cents since Oct. 5.

Analyst Trilby Lundberg believes the price will continue to go down.

The main reason for the drop is robust global production.
