Comparison scope
US mass retail, with warehouse membership and online fulfillment as related formats.
Competitive advantages
The report identifies a strong competitive advantage supported by purchasing scale, the store network and operating efficiency.
Scale and fixed-cost efficiency
Regional market share spreads logistics, warehousing, technology and purchasing-team investment across a large volume of sales.
Procurement and supply-chain efficiency
Purchasing volume, logistics and continued automation support low prices; sales volume then reinforces the scale advantage.
Shopping habits and convenience
Store coverage, one-stop shopping and an expectation of low prices support habitual use. This is a relatively soft form of customer retention.
Durability depends on turning the physical network into efficient omnichannel operations while sustaining membership value and unit-cost discipline.
