Walmart’s enormous sales volume, efficient distribution network and buying power give it a price advantage traditional grocers can’t easily match. It’s not that they don’t try hard enough. It’s that the advantage is built in – and it runs deep.
Ask a regional grocer why they can’t match Walmart on price and you’ll usually get one of two answers: Walmart buys cheaper, or Walmart sells below cost to kill the competition. Neither one is quite right, but the correct answer is essential here; you can’t fix a problem you’ve misdiagnosed.
Albertsons is the clearest case in the industry right now. Identical sales down, earnings down sharply, market share lagging – and a new executive chair, Meg Whitman, acknowledging that the company needs to reverse its market share trends. Albertsons isn’t a badly run company that forgot how to negotiate. It’s a good company trapped in a structure where the price gap isn’t a failure of effort. It’s simple arithmetic.
Walmart’s U.S. grocery sales alone were $276 billion in fiscal 2025 – more than three times Albertsons’ entire company, at $83.2 billion. Kroger, the largest traditional grocer in the country, did $147.6 billion – still barely half of Walmart’s grocery business alone. Everything that follows flows from that one fact. But it doesn’t flow in a straight line. Walmart’s advantage comes from lower operating costs, greater leverage with manufacturers and a pricing model traditional supermarkets struggle to match.
Walmart Really Is Cheaper to Run
Start with what’s legitimate. Walmart operates 164 distribution facilities in the United States and one of the largest private truck fleets in the country, built over decades. Albertsons, by contrast, operates across numerous regional divisions and 19 banners, creating organizational and distribution complexity that Walmart largely avoids.
Assortment does the same work. Costco carries roughly 4,000 items in a typical warehouse. A traditional supermarket carries 30,000 or more. Fewer items means enormous volume per item, simpler logistics, less shrink and less labor touching every case. Every extra item a traditional grocer carries adds complexity and potential cost that a limited-assortment operator can avoid.
Then there’s the cost of running the store itself. Albertsons spends about 26.3% of sales on selling and administrative expenses; Costco spends about 9.3%. The two business models aren’t directly comparable, but the difference illustrates the substantial operating cost burden traditional supermarkets carry. A supermarket has deli, bakery and meat counters, service departments and a lot of labor per dollar of sales. A high-volume warehouse club spreads many fixed costs across a much larger sales base. Albertsons’ gross margin is 27.2% — and selling and administrative costs consume 26.3 percentage points of sales. There’s almost nothing left.
And Walmart isn’t really a grocer at all. It’s a general merchandiser that sells groceries. Its general merchandise business did $113.9 billion in fiscal 2025, providing another source of sales and earnings beyond food. That broader merchandise mix gives Walmart more flexibility in managing its overall margins and pricing strategy. Costco has a different advantage: membership fees were equivalent to 51.3% of its operating income in fiscal 2025. Those fees provide a substantial revenue stream beyond merchandise sales. Traditional grocers generally have fewer comparable sources of income.
A Truck Is a Truck
One part of the efficiency story gets overstated, and it’s worth correcting because retailers hear it and stop listening. A truckload moving between the same two points costs roughly the same to operate regardless of whose merchandise is aboard. Large shippers may negotiate different freight rates, but the basic economics of operating a truck don’t change because Walmart’s name is on the bill of lading. If your entire explanation for the price gap is “Walmart gets cheaper freight per truck,” you’re missing the larger advantage.
The difference is everything around the truck. A truck that delivers and drives back empty is a truck you’ve paid for twice. Walmart’s private fleet can drop product and pick up vendor merchandise on the return leg – that backhaul is where the money is. A grocer buying delivered freight may be paying for empty return miles baked into the price. Walmart also frequently collects product itself rather than paying the vendor’s delivered price, allowing it to capture transportation efficiencies directly.
Add network density – distribution centers close to stores, shorter hauls, more drops per route – and the cost per case falls even when the basic cost of operating the truck hasn’t changed. Walmart still relies on outside carriers for substantial portions of its transportation, particularly perishables, but its scale gives it more opportunities to optimize the entire network.
THE POINT: Walmart’s advantage isn’t simply cheaper freight. It’s fewer empty miles, greater control over transportation and enough volume to spread fixed distribution costs across more cases.
Vendors Cannot Lose Walmart
The next advantage goes beyond efficiency, and it’s the one nobody likes to say out loud. For a major consumer packaged goods manufacturer, Walmart can represent an enormous share of U.S. sales. Albertsons represents a much smaller portion of the business. Losing an important national brand would hurt Walmart, but losing Walmart could mean surrendering a substantial share of a manufacturer’s U.S. distribution.
That imbalance creates leverage. Walmart’s favorable buying terms reflect both its lower cost to serve and the commercial power that comes from controlling such an enormous share of a manufacturer’s sales. Thin margin on enormous volume can be more attractive than losing that volume altogether.
Economists call it buyer power – monopsony power – in its strongest form, the mirror image of monopoly. And it can show up as a package, not just an invoice price: lower costs, promotional support, data-sharing arrangements and participation in retail media programs. Walmart Connect, the company’s advertising business, generates billions in revenue from brands seeking to reach Walmart shoppers. Those advertising arrangements are separate commercial transactions, but they illustrate how much broader the relationship has become than simply buying and selling merchandise.
Retailers feel this in their bones, which is why so many of them reach for the law. They’re thinking of the right law. They’re just wrong about what it does.
Robinson-Patman Won’t Close the Price Gap
The Robinson-Patman Act, passed in 1936, was designed to address certain forms of price discrimination between competing buyers. It generally prohibits sellers from charging competing purchasers different prices for goods of like grade and quality when the statutory requirements are met and the discrimination may harm competition.
What it doesn’t say is that everyone must pay the same price. Differences justified by genuine cost savings may be lawful, and sellers may also defend certain price differences when meeting competition. Walmart’s large, steady orders, electronic ordering systems and sophisticated inventory management can create legitimate cost-to-serve advantages.
The Act also has important limitations. Different product configurations can complicate price comparisons, although changing pack sizes doesn’t automatically exempt a transaction from scrutiny. And much of Walmart’s advantage – its own logistics, general merchandise earnings and advertising revenue – falls outside the statute’s central focus on discriminatory seller pricing.
Then there’s enforcement. For roughly a quarter of a century, federal enforcement of the Act was limited; antitrust lawyers often treated it as a theoretical possibility rather than a present-day concern. The Federal Trade Commission tried to revive it. It sued distributor Southern Glazer’s in December 2024, alleging it favored big chains over small independents; that case settled in October 2026. It sued PepsiCo in January 2025, alleging PepsiCo gave Walmart preferential pricing and promotional payments not offered to smaller retailers – the exact conduct retailers complain about – and then voluntarily dismissed its own case in May 2025.
The Southern Glazer’s settlement demonstrates that the law still has enforcement consequences. But the dismissal of the PepsiCo case also illustrates the uncertainty retailers face when looking to federal enforcement for relief.
A grocer waiting for Robinson-Patman to level the shelf price is waiting for something the law was never designed to guarantee. And if the per-load freight rate is comparable between buyers, the justification for different delivered prices must rest on other legitimate cost differences or available legal defenses. That’s a matter for regulators and courts to establish, not a strategy for a grocer.
Traditional Grocers Pay for Their Promotional Model
The next disadvantage is one the industry built itself, and it may be the most damaging because it’s largely self-inflicted.
Walmart’s vendor relationships generally emphasize a consistent, competitive everyday cost rather than the promotional cycles that dominate traditional grocery retailing. Walmart still runs Rollbacks, seasonal offers and other promotions, but its everyday-low-price model places greater emphasis on predictable pricing, steadier demand and fewer short-term adjustments. For manufacturers, that can reduce the administrative and production costs associated with frequent promotions.
The traditional grocer runs a different model: high-low. A high regular shelf price, deep promotions, and the vendor helps fund the whole circus. That funding — trade spend, the money manufacturers pay retailers to discount, display and promote — represents a substantial share of consumer packaged goods manufacturers’ revenue. Industry research has placed trade spending at roughly one-fifth of CPG sales, making it one of the largest expenses manufacturers manage.
And it leaks. McKinsey cited Nielsen research finding that 72% of U.S. trade promotions lost money. The finding dates back to 2016, but it illustrates a longstanding problem. The vendor has to plan each promotion, fund it, track it, and then fight over deductions when the grocer claims it wasn’t executed as agreed. Too much of that money fails to generate profitable incremental sales; instead, it supports margins, administration and the cost of managing the promotional system itself.
Here’s the trap. The grocer’s gross margin depends in part on vendor trade dollars, so he can’t easily quit high-low. But high regular shelf prices damage his price image, train shoppers to buy only on deal, and send the rest of the basket to Walmart. The vendor, meanwhile, has every incentive to favor a simpler, less expensive promotional relationship when it can deliver comparable sales and profitability.
THE POINT: Everyday low pricing can be more efficient for vendors and easier for shoppers to understand — while traditional grocers remain dependent on a promotional model deeply embedded in their profit and loss statements.
Digital Dilemma: Location Was the Moat… Now It’s Draining
A good regional grocer has traditionally defended himself by being close to the customer. Location was never really about the building. It was about being the closest option for the weekly shop, and for a hundred years that was enough.
Online, every store is the same distance away: your phone. U.S. online grocery sales rose 20.7% in the third quarter of 2026 and accounted for a record 20.9% of all grocery spending, while in-store sales declined. Delivery is doing most of the work – up more than 30% – while pickup grew only in the mid-single digits.
And the growth isn’t spreading evenly. Walmart, Amazon and other mass merchandisers have captured a substantial share of online grocery spending, putting pressure on traditional supermarkets that once relied on their neighborhood locations to keep customers coming back.
The big traditional chains are growing online, too – Kroger, Ahold Delhaize and Albertsons have all reported double-digit digital sales gains. But the broader market is expanding rapidly, and sales growth alone doesn’t guarantee market-share gains. What matters is whether those retailers are growing fast enough to defend their position against Walmart, Amazon and other competitors.
What’s changing is the basis of competition. In a store, almost nobody price-checks a full basket against the store down the road. Online, the basket total – plus the delivery fee and the tip – is right there on the screen, making comparison easier. Price competition gets sharper, while delivery speed increasingly replaces proximity as the measure of convenience.
The store’s job is changing too, from a place people go to a fulfillment center that happens to be near them. Kroger closed three automated Ocado fulfillment centers in January 2026, recording approximately $2.5 billion in related charges as it shifted more online fulfillment toward stores and delivery partners. Kroger hasn’t abandoned automation, but it’s acknowledged that centralized fulfillment doesn’t make economic sense in every market.
Digital doesn’t just add a channel. It shifts competition toward price, speed and fulfillment economics, areas where traditional grocers face substantial pressure from larger competitors.
How Traditional Grocers Can Compete – Without Matching Walmart
There’s an answer, and the retailers who’ve found it aren’t guessing. It’s fresh. Shoppers trust their own eyes for produce and meat, and they trust a store they’ve shopped for years to pick it for them. Walmart is a major fresh-food retailer too, but traditional grocers with strong produce, meat, bakery and deli departments can offer a level of assortment, service and familiarity that gives shoppers a reason to choose them.
Those departments aren’t a nice-to-have for a traditional grocer. They can be the reason for the trip. If the store doesn’t justify the trip, nothing else matters.
The other answer is density, and it’s the exception that proves the rule about scale. Regional grocers like H-E-B and Publix compete effectively in their home markets because they have strong market positions, dense store networks and substantial volume concentrated within those markets. That’s scale at the regional level. Albertsons’ problem is the opposite: a broad national footprint without the same degree of market concentration in many of the areas it serves.
Which is why the prescription for a traditional grocer isn’t mysterious, just hard. Concentrate resources in the markets and banners where you’re number one or number two, and reconsider those where you lack a credible path to competitive scale. Fix price perception on the couple of hundred items shoppers actually use to judge you – milk, eggs, bread, bananas, chicken – not on 20,000.
Push your own brands hard, because private label often offers stronger margins and gives retailers products competitors can’t sell. Done well, those economics can help fund sharper prices on national brands and other key items. Build profit pools beyond shelf margin – retail media, services and the customer data you already own – recognizing that these businesses won’t necessarily match the economics of Costco’s membership fees or Walmart’s advertising operation.
And make digital pay. Use pickup where its economics are favorable, price delivery to reflect its costs, and make better use of the stores you already have as fulfillment assets. A regional grocer doesn’t need to replicate Walmart’s national network to build an efficient local operation.
None of that makes a traditional grocer Walmart. Nothing will. But it stops them trying to be a smaller, worse Walmart – which is the one strategy guaranteed to lose.
