If anyone is interested, CurrencyFair are another excellent way to save money on international payments. Similar to Transferwise, you can send money fast from one currency to another at the current exchange rate with far less fees than a bank.

They also have a peer-to-peer element, where you can choose your own exchange rate and wait for another customer (sending money in the opposite direction) to accept that rate. If you are willing to wait a little longer to send your money, you can get excellent value using this feature.

They currently have an excellent sign up offer at the moment that you can access using my link: https://www.currencyfair.com/rafland/?channel=RMZIY1

(Disclaimer: I currently work there. I love the product and I know you will too:))
