Lidl is a German international discount retailer chain that operates over 12,000 stores, present in every member state of the European Union, Serbia, Switzerland, the United Kingdom and the United States. Headquartered in Neckarsulm, Baden-Württemberg, the company belongs to the Schwarz Group, which also includes hypermarket chain Kaufland.

A discount store or discounter offers a retail format in which products are sold at prices that are in principle lower than an actual or supposed "full retail price". Discounters rely on bulk purchasing and efficient distribution to keep down costs.
