What Are “Ghost Groceries” and Where Did They Come From?
Dark stores, as they’re formally known, are retail outlets repurposed as local fulfillment centers. They are “dark” because they’re not open to the public. Instead, these locations serve as high-efficiency warehouses where staff picks, packs, and dispatches online orders, especially for same-day or one-hour delivery. The term “ghost groceries” has grown informally alongside them, referring to the produce and perishables that consumers order without ever seeing or touching.
A dark store is a retail outlet or distribution center that exists exclusively for online shopping. It can be used to facilitate a “click-and-collect” service or as an order fulfillment platform for online sales. The format was initiated in the United Kingdom, and its popularity has spread to France, the rest of the European Union, Russia, and the United States. What started as a niche operational experiment has become a defining feature of how groceries reach urban households across the developed world.
The Numbers Behind the Boom
By 2024, online grocery penetration reached roughly twelve and a half percent of total grocery sales, up from about nine percent in 2020. U.S. online grocery sales reached approximately $204 billion in 2024, and for 2025, sales are forecast to reach $228 billion, with continued double-digit growth expected. The scale of this shift is hard to overstate.
The global online grocery market was valued at roughly $709 billion in 2024 and is projected to grow at nearly thirty percent annually through 2034. The dark store market itself grew from about $23 billion in 2024 to a projected $33 billion in 2025, at a growth rate of over forty percent. These aren’t gradual, incremental numbers. They describe a structural change in how food moves from growers to kitchens, and the speed of that change has outpaced most consumers’ understanding of what’s actually happening behind the app.
Speed as the Core Promise, and Its Hidden Cost
Most major delivery platforms now advertise delivery windows of ten to thirty minutes. That promise sounds impressive until you consider what it actually requires. To deliver produce in under half an hour, inventory can’t be sourced fresh each morning from a market. It has to already be sitting in a nearby fulfillment facility, pre-staged, and ready to go. Freshness, in this model, is secondary to availability.
Quick-commerce businesses that promise to deliver goods and services within ten to twenty minutes are growing twenty to twenty-five percent faster than those that deliver in hours or longer. That growth is real, but it creates a structural tension: the faster the delivery promise, the more an app depends on pre-stocked inventory rather than freshly sourced produce. Operating dark stores isn’t without hurdles, and managing perishables demands sophisticated cold chains, while labor costs and real estate in prime locations add pressure. When those pressures mount, quality control is often where corners quietly get cut.
The Algorithm Picks Your Tomatoes Now
In a traditional supermarket, you reach past the soft peach in the front and grab the firmer one behind it. That small act of quality selection is so automatic it barely registers. In a dark store, it doesn’t happen at all. Picking staff work under algorithmic systems optimized for speed and inventory routing, not for spotting a browning bunch of bananas or a wilting head of lettuce.
Delivery apps rely on algorithm-based picking systems that prioritize order completion time and route efficiency. The software tells a picker exactly where to go and exactly what to grab. There’s rarely a built-in mechanism for a worker to override the system because a tomato looks a day past its best. Fresh and perishable goods now command roughly forty-one percent of the online grocery market share in 2024, demonstrating growing consumer trust in cold-chain logistics. That trust, though, is built more on habit and convenience than on any guaranteed quality standard across all platforms.
Food Waste, Expiry Windows, and the Near-Date Problem
Food waste is already a serious problem in conventional supply chains, with losses in fresh produce reaching up to roughly a third of total supply before food ever reaches a consumer. Fast-turnover delivery systems introduce their own specific risks. When a dark store needs to clear near-expiry inventory to manage stock rotation, algorithmic systems may move those items toward outgoing orders rather than flagging them for disposal.
A lack of control over product quality and freshness is identified as a factor that may hamper the online grocery market’s growth. Still, artificial intelligence is increasingly being used to help, with AI optimizing inventory management through predictive analytics. The technology can theoretically reduce the near-expiry problem by forecasting demand more accurately. Whether platforms consistently apply these tools to benefit produce quality or primarily to reduce their own waste costs is a question consumers don’t have easy visibility into.
Why Shoppers Keep Coming Back Anyway
Surveys find that up to roughly seventy-two percent of customers prefer to buy groceries online due to convenience or time constraints. That figure reflects something genuine about modern urban life. For a working parent, a time-strapped professional, or someone with limited mobility, the trade-off between convenience and perfect produce quality often lands firmly on the side of convenience.
In 2023, the vast majority of American households purchased groceries online over a three-month period, yet most continued regular in-store shopping. Consumers strategically use online for convenience and stock-up trips, while preferring in-store for immediate needs and fresh product selection. This is a nuanced picture. People aren’t replacing the supermarket entirely. They’re layering delivery on top of it, using apps for staples and packaged goods while still going in-store when freshness really matters to them. The question is whether that distinction holds as delivery becomes even more dominant.
The Gig Economy Layer and What It Means for Accountability
The success of quick-commerce companies depends heavily on delivery riders, and in most cases, those riders are gig workers who face challenges related to job security, variable compensation, and long working hours. Retaining skilled and professional riders is also a persistent challenge for these companies. This matters beyond the social economics of gig work. A system with high worker turnover and compressed delivery timelines is also a system with less institutional knowledge about proper handling of perishables.
In 2022, there were roughly 1.7 million people employed as delivery drivers in the United States, with projections showing continued growth reaching close to 1.9 million by 2031. The pipeline of gig labor is growing fast. Nearly ninety percent of retailers are expected to utilize crowdsourced delivery methods for specific orders by 2028. As the workforce expands and turnover continues, consistent product handling standards become harder to enforce across a distributed, app-based network where no central employer sets quality norms the way a traditional grocery chain might.
Consumer Trust, Sourcing Transparency, and What Comes Next
Fresh food remains a key priority for many consumers, especially those who view it as integral to health and wellness. Shoppers are making deliberate trade-offs between quality and affordability. For delivery platforms, this is both a vulnerability and an opportunity. Consumers who feel repeatedly disappointed by poor produce quality don’t always complain formally. They quietly switch apps, or start reverting to the store.
Advancements in cold chain logistics, smart packaging, and AI-driven inventory management are improving the efficiency of online fresh food distribution, reducing spoilage, and ensuring more timely delivery of perishable goods. The technology to do this well does exist. AI is being used to forecast demand, route deliveries, and reduce waste. Automated fulfillment centers are also scaling up the number of orders processed per hour without increasing headcount. The real question isn’t whether the tools are available. It’s whether platforms are willing to invest in quality verification with the same energy they pour into delivery speed.
Conclusion: Convenience Has a Flavor, and It Isn’t Always Fresh
