Free international transfer up to £500 when you join Wise (plus get £50 after you refer 3 people). It is a very useful tool that I used at least three times. So, getting 3 people to sign up is easy! Wise (formerly Transferwise) are a fintech company who offer money transfers among other services. When you sign up to Wise using my referral, your first international transfer between £200 and up to £500 will be free.
