its a simple matter of good business that they keep the price high.
When you have a business you need to stay in business. To do so means that when you sell your product, that you have enough money to pay your employees, pay your bills (rent, power, taxes, etc), and to pay to restock your business.
Right now with the market being so crazy their wholesale cost to resupply may spike any day. If they sell the gas for cheap and then dont have enough money to buy new gas when the wholesale cost goes up, they will loose money. They will then have to make up EXTRA gross to catch back up on the net.
Also keep in mind that gas stations dont necessarily buy gas every day, especially in the higher grade fuels.

Except it seems like when crude goes up, gas station prices go up before the day’s done.
