there are 3 Halifax savings accounts added, not all 3 fulfil every search criteria which is why they may not show on certain pages.
it all depends on what kind of account you are looking for, Halifax's monthly saver do not allow lump sum deposits, RaboDirect do. Halifax do allow with their [broken link removed] account to deposit "any amount from €2,500 up to €250,000" but the interest is 4.00% AER and not 5.00% with RaboDirect (on amounts of €10,000 or less), but changes to 3.75% for balances from €10,000 to €1 million. so it all depends on how much you want to save etc.
