Gas prices are continuing to soar across Tennessee and the United States.
Abdi Redi, a local cab driver, said that the rise in gas prices has made it hard because it reduces his family's income.
"I used to fill $30 every day. Right now it's $40," Redi explained.
Spending $10 more a day, seven days a week, has caused Redi to spend another $300 per month on gas alone.
Jim Lott, Triple A manager, said that the improving economy and oil speculators are to blame for the rising prices.
"When speculators start to get back into the market, they speculate that we're going to buy more gas, and we're going to drive our cars more, so that helps to drive up pricing," Lott told Nashville's News 2.
According to AAA, a gallon of regular unleaded is now $3.60 in Nashville, up 23 cents from just last week.
Some of the lowest gasoline prices posted on GasBuddy.com were from Costco and Sam's Club.
At non-membership gas stations, the lowest price listed for a gallon of regular unleaded was $3.49 a gallon at the Mapco on Nolensville Pike and Tusculum Road in south Nashville.
Compared with last month, prices are nearly 50 cents more.
Experts believe prices will continue to rise at least through April.
A number of factors are to blame, including a switch to summer blend fuel, refinery maintenance that typically occurs in January and February, and operational problems from Superstorm Sandy.
