HOLLAND, MI (WHTC) - More fodder for the conspiracy theorists is provided by this week’s gasoline price survey along the Lakeshore. This morning’s polling of Holland area stations provided a per gallon average of $3.59, with only five of the 38 retailers canvassed not posting that mark on their marquees. The mean is 15 cents higher than last Friday, and reflects a 30-cent spike in fuel that came up on Wednesday morning. Triple-A’s daily survey had marks of $3.45 nationally and $3.48 acrossMichigan, increases of six and 10 cents, respectively.
