Euro Transfers

Hi,
I'm in the process of buying an item from Spain and I'm wondering what the best option is for sending money. I bank with BOI but I find it hard to work out their SEPA transfer fees. I have a CurrencyFair account that I used for Sterling purchases before and it was very useful.
I'm just wondering if I should use BOI 365 or CurrencyFair to send money to another EU country.

There's no fees for Euro transactions within Euro zone.
Just normal 365 bank transfer as you would do with a payment in Ireland, or card payment (if offered).

If you are buying an item from Spain, then presumably you are paying in euros

There are no hidden fees for sending euros with the SEPA area and assuming you have a personal account

Thanks folks
