saint said:On why prices were jumping 30c or more in very short periods of time: North Carolina state law is that a station cannot sell gas for under the wholesale prices. As demand went up, stations went dry quickly. When the new trucks came in with fresh gas, it was at the higher wholesale prices of 3$. The reason why some stations jumped while others stayed low: for a short period of time a station charges the price it payed for the gas presently in its tanks. So some still had leftover of the cheaper wholesale price so they could sell it cheaper. Once they filled up with the higher priced gas they had to increase price.
IF this were true where I live, all the gas stations in town must have had a 6AM delivery on Monday, a 6AM delivery on Wednesday followed by a 1300 delivery on Wednesday. That's when the prices jumped. Personally, I've always wondered how the bought gasoline sitting in the tanks underground can go up in price. Never understood that.
