It's likely not free (but probably not outrageous either)... Last time I did something like that the transaction cost was small (< €10) but the human element was large due to approvals (think i was in the bank over an hour and it involved 4-5 bank staff to make it happen). Anti-money laundering processes cost money and many of the crypto-currencies ignore this for now / pass the problem to the fiat ⇆ crypto exchange operators.
On the flip side, I saw a payment go through for one our suppliers today. $50 invoice. > $25 processing fee because it was a european bank processing a USD transaction. :/
