If you’re planning on a Fourth of July road trip then you can shave a few dollars off of your fuel budget. Gas prices have hit a five-month low, with some areas of the country reporting prices at under $3.00 per gallon. Lucky residents in Greenville, S.C., can find gasoline for $2.69 a gallon. I haven’t seen prices under $3.30 a gallon here in the metro Phoenix area but I haven’t looked very hard. How much are gas prices in your neck of the woods?
