Comment on the May 19 prediction: It was CORRECT, as prices continued to fall. Lowest as of the moment is $2.52 in Lowell, which is pretty close to the $2.49 floor in the prediction.

Thursday, May 27, 2010, 3:00PM: With Memorial Day weekend almost here, will the retailers raise prices on Friday? If my calculations are correct, the 0-cent margin price is around $2.50, and a price hike would be in the neighborhood of $2.69. That’s quite plausible, given that prices are in the $2.52-$2.72 range now. So, I would fill up tonight, just to be safe, and, just for the heck of it, let’s make it a prediction: price hike on Friday. — Ed Aboufadel
