Our store is located on the west coast of Canada. We have received a few messages asking if we are American because our prices are mostly in USD. We price this way because it is easier for people overseas.
As we are an online Canadian based store and dealing with the world market, we use the U.S dollar has the benchmark. Worldwide it is easier for people to convert from their dollar to U.S funds. In fact, many people have the conversion factor memorized, so where ever they go they can convert their dollar to another.
