Hello all - Does anyone know where or how I can swap my British pounds for Euros without having to go to a bank. I have a trip to London coming up and would like to use it for my trip. I could go to the bank, but the issue is that the transaction cost is around 10%. I would love to be able to trade it with someone who has left over Euros. Not sure if this is possible. Thanks for the help in advance. BTW, I live in the US.
