Great advice from MSE on how to send money overseas. Includes a link to the post office international transfers, which offer better rates than banks, no fees, and arrives in a similar amount of time. Bloody brilliant.

Great article from MSE on the best cards (credit or debit) to spend and withdraw cash on overseas. Best for me is currently N&P.
