ID is not a major problem sending to a private seller but would be better if it could be avoided.
I remembered another alternative.
I can easily buy google play, itunes, spotify, etc... vouchers with cash.
Are there a market for those?
Not sure who wants $320 of gift cards though
The ID you provide to WU/Moneygram isn't provided to the recipient, it's just held on file for their reference.
WU to Australia is $5 from memory, happy to sell if you still need to.
