It was still $3.899 at our local Chevron station (note that I generally buy my gas at COSTCO so I hardly ever pay those sorts of prices, but you always see people gassing-up at these high-cost, brand-name stations) this morning on my way to work.
Last week my wife and I were driving back from Washington state (we had to attend a funeral) and on one of our stops there were two stations across the road from each other. One had gas for $4.399 for regular and the station across from it was exactly a dollar less, at $3.399, yet there were a line of cars at both stations filling-up.
