Orla,
At a guess, I would say that BOI will try and steer you towards their unit linked SmartChoice Plan/Special Saver Account where they offer you a 25% 'bonus' based on the the amount of regular contribution in the first year.
This is not good value for money as they are basically giving you back your own money, that they will take off you in excessive charges.
If you are looking for this type of investment/savings product then you would be better off with the Eagle Star or Quinn Life offerings.
Take your time. You don't have to sign up today.
