Just made a transaction to China via WUMT - did it online as service no longer available - also cheaper and easier than using a bank.

You have to create an account etc - then ring the free number at end to confirm payment - fee is $28

The fee isn't too bad - I payed $8.?? something for the IMO + registered post.  My biggest concern is PBR as pretty much everything else is PP or Visa.  I don't recall seeing WUMT as an option for them (even though the IMO is WU as well).
