What is "megamart"

Megamart was an Australian chain of stores owned by Coles Group (then Coles Myer) that sold electrical and furniture items. It was a sub-store of department store chain Myer, so it was also known as Myer Megamart or Megamart by Myer. Some Megamarts were bigger than whole Myer stores alone.

According to Business reporter Stephen McMahon, the reason Megamart closed was that "Its small footprint meant it struggled to compete with rivals such as Harvey Norman and Dick Smith - while cannibalising Myer's own sales."
