mamade, i retrieved 300USD from an RBC in Canada billed at 409$ CAD = 1.363333 conversion rate last week (22 jan).
I find if you can get 90 + JMD$ or more per 1CAD$ it is worth it to just convert straight there, and then I base my whole weeks negotications and dealings on an almost 1CAD - 100JMD rate for easy and quick mental calculations.
