Dunnes Stores has asked the High Court to rule on what is the definition of groceries in a row between the supermarket chain and a discount retailer. Dunnes wants the court to enforce a restriction on what a Mr Price outlet in Carlow town can sell which the supermarket says is a requirement of the lease granted to the discount store. Dunnes says groceries are more than just food and includes low-cost, non-durable repeat household items. Mr Price accepts groceries means food but opposes Dunnesâ contention that it extends to other items. The case concerns the opening last October of a Mr Price store in the Barrow Valley Retail Park in Carlow where Dunnes is the anchor tenant in its 65,000 sq ft premises.
