Just filled my tank at the USA Gas station in Blaine, WA. Purchased 9.461 US gallons for $20.62 USD.
This works out to 35.81 litres for $25.78 CAD wwhich equals 72 cents Canadain a litre. This is 25 cents a litre cheaper than in Canada.
The Vancouver gas stations are ripping us off big time. I avoid them as much as I can. And when I do buy gas here in Canada I buy it in amounts of $5 or $7 a time so the high costs of the credit card transactions eats away at their profit.
