Are they always better in Arcade than in other areas ?
also I heard about a money changer finder website, does
someone try it already?
I think the rates in Arcade are pretty good. Do note that FX
rates vary even among the money changers in Arcade. So you can shop
for the best rates.
I have never seen the rates in Chinatown, so I am unsure if they
offer better rates.
Like what Ditzy said, it matters little if you are changing
small amounts, i.e. less than 20k. Don't swear it because of a few
pips.
Never hear about the online money changer finder. Do let us know
how is it.
