So here in Canada this weekend is the May Long Weekend (Victoria Day on Monday) and coincidently (or not) today gas prices here in edmonton went from 115.9/liter to 122.9/liter. (4.39gallon and 4.66gallon for those in the US)
The big companies state that they don't jack up the prices for holidays and long weekends but I'm not inclined to believe them.
So today I created a spreadsheet and I will be tracking when gas prices go up and down and when they do so. I'll see how many of these changes are in fact occurring around holidays.
Have you noticed this trend?
