Edeka The Edeka Group is the largest German supermarket corporation, currently holding a market share of 26%. Founded in 1898, it consists today of several cooperatives of independent supermarkets all operating under the umbrella organisation "Edeka Zentrale AG & Co KG", with headquarters in Hamburg. There are approximately 4,100 stores with the Edeka nameplate that range from small corner stores to hypermarkets.

Dealz Dealz is a chain of discount retail stores predominantly in the Republic of Ireland and Spain, offering a range of general merchandise products, the majority of which are at the fixed price of €1.49. Since the Irish rounding of cash transactions on  28, 2015 (2015--) , the company now sells its goods at €1.50 which doesn't make much of a difference in their net income due to the one cent difference.
