Foreign Exchange Charges

With the British Pound at its weakest for a long time, it has got me wondering what fellow InterNation members do with regard to mitigating costs relating to foreign exchange, not just Brits, but everyone.
I would imagine that most members of InterNations have a strategy when transferring money but I also suspect many others are unaware of the options open to them, just like I was....

I was recently charged by my UK bank to send the money to Thailand, charged for an International transfer, charged to receive in Thailand by my Thai bank and finally charged to withdraw in Thailand at the ATM.
4 lots of charges in total - there may have been more.

Any thoughts from fellow InterNations members?
