The price at the pump quietly went up over eight cents at some gas stations across Windsor in the past few days.

The price at most Windsor stations Tuesday was around $1.27 a litre.

“Extremely high and it's not necessary," says Windsor driver Marleen Shaw. "Last week I paid $1.17 and $1.13 and now it's $1.27 to $1.29. That's terrible."

Some analysts say it doesn't add up.

“Prices have gone well beyond what is economically expected," Dan McTeague, founder of tomorrowsgaspricetoday.com.

McTeague says despite lower holiday weekend prices, recent gas prices do not reflect the standard theory of supply and demand.

“Throw those theories out the window,” says McTeague. “They have been completely and utterly ruined and of course the United States is trying to put the proverbial genie back in the bottle through the Dodd-Frank Act."

Windsor economist Mark Meldrum agrees, saying supply is up and demand is down with more fuel efficient vehicles on the road.

“There is no inventory reason why,” says Meldrum. “There is no supply reason why. There is no demand reason why. So the only thing left is profit."

To Meldrum, the numbers don’t add up.

“It's showing up in demand numbers. When you have 2013 gasoline demand at 2003 levels, lower than the depths of the recession,” says Meldrum. “We have to say that our behaviour has changed but prices just aren't reflecting it."

Meldrum says there isn't much motorists can do except grin and bear it.

“I think I'm used to them now more than anything but still upset," says Shaw.

It could still be worse for Windsorites. In Vancouver Tuesday, a regular litre of gas was at $1.44.
