I'm sure gas prices are dropping all over the country.  It's a nice oasis in a sea of economic turmoil.

But I've noticed something odd though here in North Carolina: the price disparity is larger than I have ever seen it before.

At one station near my house, the price of regular unleaded is $2.99 a gallon.  Go another quarter mile, and the price at other gas stations is $3.29.  Then, further down the block, it is $2.98.  And further still, $3.32. 

Whaddup with that?  Anyone know?
