necessary for one-stop shopping, supermarkets are large stores that typically have at least 10,000
square feet of selling space.
26. Supermarkets allow customers to purchase most or all of their food and grocery
shopping requirements in a single trip to a store that offers substantial products in each of the
following categories: bread and baked goods; dairy products; refrigerated food and beverage
products; frozen food and beverage products; fresh and prepared meats and poultry; fresh fruits
and vegetables; shelf-stable food and beverage products, including canned, jarred, bottled, boxed,
and other types of packaged products; staple foodstuffs, such as salt, sugar, flour, sauces, spices,
coffee, tea, and other staples; other grocery products, including nonfood items such as soaps,
detergents, paper goods, other household products, and health and beauty aids; and, to the extent
permitted by law, wine, beer, or distilled spirits. Supermarkets also offer customer service options
including deli, butcher, seafood, bakery, prepared meals (e.g., sushi, hot bar), or floral counters.
27. Supermarkets recognize other supermarkets as a distinct type of food and grocery
retailer. For example, supermarkets track and respond to other supermarkets’ promotions and
customer-service options. When determining their pricing, supermarkets primarily consider the
pricing of other supermarkets. This is true for Respondents. Kroger predominantly price checks

28. A relevant antitrust market need not include all substitute products or services. The loss
of competition between a narrower group of substitutes can cause harm, making the narrower
group a properly defined antitrust market. The hypothetical monopolist test is a tool used to
determine if a group of products (i.e., type of retailers) is sufficiently broad to be a properly defined
antitrust product market. If a single firm (i.e., a hypothetical monopolist) seeking to maximize
profits controlled all sellers of a set of products or services and likely would undertake a small but
significant and non-transitory increase in price or other worsening of terms (“SSNIPT”), then that
group of products (i.e., type of retailer) is a properly defined antitrust product market.
29. A hypothetical monopolist of supermarkets likely would undertake a SSNIPT on
consumers. In response to a SSNIPT, supermarket customers would not shift enough of their
purchases to non-supermarket retail formats to make a hypothetical monopolist of supermarkets
unlikely to undertake a SSNIPT. The reason consumers would not shift a significant enough
volume of purchases is because these non-supermarket retail offerings provide a very
differentiated customer experience. For example:
• Club stores (e.g., Costco, Sam’s Club) require membership fees, typically offer
larger package sizes, and frequently rotate their product assortments. Club stores
have more square footage but offer far fewer food and grocery SKUs than
supermarkets. Club stores also have fewer store locations than supermarkets,
requiring consumers to travel longer distances.
• Limited assortment stores (e.g., Aldi, Lidl) offer a differentiated, narrower selection
of product SKUs. Most of the SKUs limited assortment stores offer are private label
(i.e., store brand) as opposed to national brands. Limited assortment stores often
offer products on a rotating, limited time, or seasonal basis, meaning customers are
