Tesco  sell a fairly good selection of wines from around the world and they will deliver to your door if you are within a few miles of one of their shops. Not all Tesco shops do home delivery but you can easily check to see if they will deliver to your exact location on the Tesco Ireland website
Tesco home delivery charges vary - depending on the day of the week - weekends are dearer - but it is no more than €8 euro.
