Category killerA category killer is a retailer, often a big-box store, that specializes in and carries a large product assortment of a given category. Through their wide merchandise selections, low pricing, deep supply, large buying power and market penetration, they have a comparative advantage over other, smaller retailers, and can greatly reduce the sales of rival retailers within that category, in the area and beyond it. In essence, they are a price- or discount-based specialist mass-retailer.

Dow Jones Industrial AverageThe Dow Jones Industrial Average (DJIA), Dow Jones, or simply the Dow ('daʊ), is a stock market index of 30 prominent companies listed on stock exchanges in the United States. The DJIA is one of the oldest and most commonly followed equity indexes. Many professionals consider it to be an inadequate representation of the overall U.S. stock market compared to a broader market index such as the S&P 500. The DJIA includes only 30 large companies. It is price-weighted, unlike stock indices, which use market capitalization.
Digital economyThe digital economy is a portmanteau of digital computing and economy, and is an umbrella term that describes how traditional brick-and-mortar economic activities (production, distribution, trade) are being transformed by Internet, World Wide Web, and blockchain technologies. The digital economy is backed by the spread of information and communication technologies (ICT) across all business sectors to enhance its productivity. A phenomenon referred to as the Internet of Things (IoT) is increasingly prevalent, as consumer products are embedded with digital services and devices.
Online grocerAn online grocer is either a brick-and-mortar supermarket or grocery store that allows online ordering, or a standalone e-commerce service that includes grocery items. There is usually a delivery charge for this service. Brick-and-mortar supermarkets that have built internet channels to better service their clients are known as online grocers. Online grocery delivery services are available throughout Europe, Asia and North America, mostly in urban centers. The online ordering is done through e-commerce websites or mobile apps.
DelicatessenTraditionally, a delicatessen or deli is a retail establishment that sells a selection of fine, exotic, or foreign prepared foods. Delicatessens originated in Germany (original: Delikatessen) during the 18th century and spread to the United States in the mid-19th century. European immigrants to the United States, especially Ashkenazi Jews, popularized the delicatessen in U.S. culture beginning in the late 19th century. Today, many large retail stores like supermarkets have deli sections.
