No idea whether you guys know or not, sometime exchange rate in the bank is better than money change. BCA Bank or Panin Bank. It's easy to find BCA Bank since it has quite few branches around nagoya area. The drawback is that gotta que lor. Why the bank exchange rate is sometime better than money change? Because at the end of the closing margin day, those money change still have to go to the bank to exchange the notes what? Then of course, if you are looking to exchange during the weekend, rate isn't competitive, likewise the money change counters. Exchange rate on the weekend is definitely consumers loses. B'cos the local money change wants a safety in case of hyper up-down trend changes on the next week market. Then they will suffer loses. So better change your $$$ before the weekend.
