Aldi (stylized as ALDI) is the common brand of two leading global discount supermarket chains with over 10,000 stores in 18 countries, and an estimated combined turnover of more than €50 billion. Based in Germany, the chain was founded by brothers Karl and Theo Albrecht in 1946 when they took over their mother's store in Essen, which had been in operation since 1913.
Aldi stores can be found in the United States.
