They probably started listing their fees after this lawsuit from your neck of the woods: http://www.cbc.ca/cp/Oddities/061024/K102418U.html

The brokerage fee would be roughly 40$ for me, when it only costs me 20$ of gas to go pick it up in Maine. And then I will be able to fill up in Maine and save close to 15$ on a gas tank.

The alternative is find a place that ships via USPS since Canada Posts has a flat fee of 5$ on brokerage fees.
