The story
The company was known as Far Eastern Geant Co., Ltd. (same corporate name in Chinese), doing business as Far Eastern Géant (愛買Géant/愛買吉安; Àimǎi Jí'ān). The store began offering a membership card in 2004.
In September 2006, Groupe Casino sold its 50% stake, which was worth $738 million New Taiwan dollars, to Far Eastern Department Stores. In 2006, Far Eastern Geant was still the third largest hypermarket chain in Taiwan, with over NT$13 billion in sales; this was an 11% increase from its 2005 figures. At that time the company was still making losses.
