TransferWise is an international payment system that I've used. I'm not affiliated with them, but I sent money internationally many months ago, and then I received money internationally (from a different company) through them. I plan to keep using the service because it's quick and easy. I really prefer it to Western Union, MoneyGram, and bank wires.
If anyone wants my referral link, I'd be glad to PM it. They are giving 1 free transfer to new members, but I believe you need a referral link. With the new member offer, you can send up to 500 GBP for free.
I will remove this if it's not allowed.
