Consumers are taking another huge hit in 2013. First, the two percent Social Security tax hike began the year. Now, gas prices are soaring ever closer to $4 a gallon and have jumped 51 cents a gallon since Dec. 20.

According to the Oil Price Information Service, the national average for a gallon of unleaded was $3.21.9 on Dec. 20, 2012. Today, that price is $3.73.0. While there has been a steady increase, prices shot almost 9 cents just over the weekend.

This President’s Day also marked a full month of rising gas prices every single business day, following a very small early year drop. Gas prices began rising Jan. 18, from $3.29.3-a-gallon, and have soared since. If this increase continues, gas prices could threaten or even top the all-time high price of $4.11, set in 2008.
