Zellers was a Canadian discount store chain founded by Walter P. Zeller in 1931. It was acquired by the Hudson's Bay Company (HBC) in 1978, and after a series of acquisitions and expansions, peaked with 350 locations in 1999. However, fierce competition and an inability to adapt during the retail apocalypse resulted in Zellers losing significant ground in the 2000s.

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.
