John Lewis - the “upmarket” department store currently has no shops on the island of Ireland - but one is planned for the Sprucefield centre near Lisburn in Northern Ireland. It is not expected to be ready for a couple of years.
In the meantime - online shoppers in Northern Ireland can order from The John Lewis website and get FREE DELIVERY on all orders. John Lewis sell electrical items, designer clothes, beauty products, furniture, rugs, toys - a one stop shop for almost everything! A great place to arrange your Wedding present list online too.
Republic of Ireland customers - I am afraid - cannot get deliveries from John Lewis - but you could do your online clothes shopping at any of the sites below instead - who all deliver to Ireland.

Gareth Thomas, John Lewis’s director of retail design and development, has previously said that  the company viewed Sprucefield as the only viable location for a store in Northern Ireland. However, the firm is also keen to open south of the border.
(Probably Dundrum).

There is only the one House of Fraser store in Ireland - that is in the Dundrum Town Centre in Dublin.
Hous of Fraser sell a range of top designer label clothes for men , women and children -  as well as accessories such as hangbags, belts and sunglasses . Perfume ,cosmetics  and other beauty products are also available. They may not be cheap - but hey we all need to treat ourselves or someone special now and again.

There is no HouseofFraser.ie web site - but the House of Fraser UK site will deliver some items to Ireland. Larger items such as furniture and electrical goods will not be delivered to Ireland - or Northern Ireland - all other deliveries are charged at £15 GBP per order to Ireland and £10 GBP to  Northern Ireland.
