I need to change £200 into Euros, wheres the best place for me to do it?

-Hi, im going to Ireland tomorrow and need to change 拢200 into Euros, whats the best shop for me to do it in? And how many Euros do you think it will get me?Whatever you do, do not change it when you go to Ireland as it will be much more expensive than in the UK. You can try at post offices or banks as they usually have the best exchange rates. Also if you are going by plane you could always change it at the airport.
The Post office. 0% Commission. 拢200 is about 226 Euros. Ireland is damn expensive, you may want to take some more.
