total cost of excise,customs duty and vat on a case of wine from eu to ireland (unacccompanied-shipped) ?

i want to see if it is cheaper to go on ryanair to fetch a case than it is to have it shipped as accompanied wine pays nil and the fare can be as low as 5 euro
no roddy - if you do not travel with it then excise duty and vat are all payable !!
i think it is about 3 to 4 euro per bottle in total but would like to know exactly
