In a previous picture the cost of a gallon of regular unleaded was $2.819--due to reasons, like suddenly finding a trillion barrels more oil reserves, increased production capacity during the snowy season, reduced demand since nobody needs oil for heat when it's cold outside, or some other reason related to the market (maybe just since oil companies are in such stringent competition?), a gallon is nearly a dollar less in this picture of the day.

kamoranakrre wonders how soon before it's back to $2.819 again. Probably sooner than $0.999, anyway.
*Well, more like 29.798% since three digits after the decimal point are clearly needed when dealing with petrol prices.
