I found last week to be rather confusing. Why did prices go all the way back to $1.79? Why did prices go back down on Thursday, at least on the north side of town? My calculations say $1.69 with a 20-cent margin, and a $1.50 with no margin, and since we are close to $1.69, there should be no price hike this week. That would be WRONG, as the price hiked to $1.80 in Standale on Tuesday.
