Sending money to the UK

hi, can anyone tell me the cheapest way to send money to the uk.

i'd like to send 2k, euro, to my sister.

i was looking at paypal... but theres some sort of currency conversion charge....

any advice.

i'm asuming my bank, ptsb, wouldn't be able to transfer it to her account, BOI.

Course they can - should be a minimal charge too if you don't send it same day value.
