If your an Economy Expert just think as a normal consumer.  Don't need all those theories and supply and demand stuff.

 On Friday driving through Middleburg I noticed the Local Racetrac felt honored to raise it's Diesel price to $4.29.  I did the normal sigh and thanked god for Murphy Oil and the additional 3 cents a gallon discount.  Then Saturday morning I drive by and what do I see?  Yet another raise of 6 cents per gallon to 4.35!  I really thanked god then because coming back to Murphy Oil it was only (thatts a funny word when talking about diesel, especially since not 15 years ago it basically was a throw away item and cheap) 4.18 minus the 3 cents so I paid an outstanding 4.15 a gallon.  Then yesterday I drive through Middleburg again and suddenly to my surprise There was that big ugly Racetrac sign once again only this time in less then 24 hours it had dropped to 4.31 a 4 cent decrease.  I'm thinking PRICE GOUGE big time.  Regular gas never went up at that station all weekend yet diesel is bouncing like a basketball.  On a Weekend when our good friends on the Commoties Market are home catching a taxi and not driving the price up the price in Florida steadily goes up.  Here's another instance at the Shell station on the corner of Blanding and Madison I drove by last night at around 7 p.m. price for regular was 3.69 this morning at 6:25 a.m. it went up to 3.79 a whole dime.  Did the Commotities Market have a secret meeting last night and drive the price up?  Why are these stations getting by with this. Americans screwing Americans you got to love it.

Just curious for some insight on pricing.
