In addition to its main customer base in Ireland, the chain also has operations in Spain, and formerly in England and Scotland. The format of the chain's stores include a grocery supermarket operating alongside a clothing/textiles store. The grocery operation only operates in Irish stores and some Northern Irish stores, although some limited grocery ranges can be found in the Spanish stores. However some stores contain only textiles, while some (more rarely) contain only a supermarket. Dunnes Stores' original own brand of groceries was sold under the St Bernard brand for many years, becoming an Irish household name, but was rebranded as "My Family Favourites" in 2013.
