A category killer is a retailer, often a big-box store, that specializes in and carries a deep product assortment within a given category and through selection, pricing and market penetration obtains a massive competitive advantage over other retailers.
Once typically found in power centers, increasingly they are found in or adjacent to (as an outbuilding of) repurposed traditional malls.
