To your point NOLA, the word gouging may be a bit harsh. Lets call it taking advantage of the situation.
OK, I left the BOL today and as I drove south towards Philly the prices started to drop for example:
At 0 miles 87 was $3.95
20 miles south 87 was $3.85
100 miles south 87 was $3.81, and
184 miles south 87 is $3.79.
All prices were along the PA Turnpike. If you got off the Turnpike I am sure there would be spots 5 cents less then the $3.79.
Typically, (for the last six years that is) gas up at the BOL was the same price as Philly. Now their is a large price difference.
