# Private label as a power play, not just cheap goods
Walk into an Aldi store and roughly 90% of what's on the shelf carries an Aldi brand name, not CocaCocaCustomer Acquisition Cost: total sales and marketing spend divided by the number of new customers acquired over the same period.View full definition →-Cola, not Kellogg's, not Procter & Gamble (P&G). That is not a discount gimmick. It is a deliberate structural choice that strips national brands of their leverage and hands Aldi control over price, quality, and shelf space all at once. Once you see private label this way, store-brand expansion stops looking like a budget category and starts looking like a bargaining chip.
This lesson reframes private label (also called "store brand," "own brand," or in the UK "own label") as a strategic weapon retailers use to shift power away from manufacturers, not just a cheaper alternative for shoppers.
Private label products are made for a retailer, sold under the retailer's own brand (or a house brand it controls), rather than under a manufacturer's national brand. The retailer, not a company like Unilever or Nestlé, owns the recipe, the packaging, and the customer relationship.
Crucially, the retailer usually doesn't manufacture the product. It contracts a co-packer, sometimes even the same factory that makes the national brand equivalent, to produce it to spec. So a store-brand cereal might roll off a production line owned by a large contract manufacturer, or even by a branded competitor with spare capacity.
This matters for power dynamics: the retailer captures the margin that would otherwise go to a branded manufacturer's marketing, R&D, and profit line, while outsourcing the operational risk of production.

Private label flips this. When a retailer builds a credible own-brand alternative, it gains three things simultaneously:
Negotiating leverage. If Tesco can credibly threaten to delist a national brand and replace it with a private-label version customers accept, the manufacturer's bargaining position weakens. This is sometimes called "category captaincy" leverage: whoever controls the shelf narrative controls the negotiation.
Margin capture. Private label typically carries higher gross margins for the retailer than reselling national brands, since there's no manufacturer brand markup to pay for. Estimates commonly cited in industry analysis put private label margins for retailers at several percentage points above comparable national brands, though exact figures vary widely by category and are not publicly standardized.
Customer lock-in. A shopper loyal to "Kirkland Signature" (Costco's private brand) is loyal to Costco, not to a manufacturer. That loyalty is harder for a competing retailer to poach than loyalty to a national brand sold everywhere.
Aldi built its entire model around private label from day one. With roughly 90% private label penetration (a figure widely cited in retail trade press, treat as approximate), Aldi doesn't negotiate with big FMCG brands much at all. It negotiates hard with a small set of suppliers for high volume, consistent quality, no-frills SKUs (stock keeping units, unique product identifiers). The strategic effect: national brands have almost no route into Aldi, which caps their reachreachThe number of unique people exposed to your message in a given period.

Costco uses Kirkland Signature differently. Costco stocks fewer SKUs per category than a typical supermarket, often just one or two options. When Kirkland Signature enters a category, it doesn't compete alongside dozens of brands, it frequently becomes the dominant or only option shoppers see. Costco has stated in public disclosures that Kirkland Signature represents a significant and growing share of sales, commonly cited as around 30% of total sales, an estimate worth treating cautiously since methodology varies.
Tesco, the UK's largest grocer, runs a tiered private label strategy: budget lines, mainstream own-brand, and premium tiers like "Tesco Finest." This lets Tesco compete with national brands across the entire price spectrum simultaneously, squeezing manufacturers from above and below.
Here is the applied skill: when you see a retailer's private label share rising, ask what it signals about bargaining power in that specific category, not just about consumer thrift.
Rising private label penetration typically signals:
A useful heuristic: private label share above roughly 20 to 25% of a retailer's basket generally indicates the retailer has meaningful structural leverage over its remaining branded suppliers, not just a value-conscious customer base. In parts of Western Europe, private label share of total grocery sales is commonly estimated around 35 to 40% (source: Private Label Manufacturers Association, PLMA, figures should be checked against their latest report as they update periodically), notably higher than the historically lower US average, though the US gap has been narrowing.
National brand manufacturers haven't stood still. Their main responses:
Innovation speed. Brands can move faster on genuinely new product formats than private label, which tends to follow proven categories. A private label lemon and ginger shot only appears after the branded version proves the category works.
Brand equity investment. Heavy advertising still works to justify a price premium for shoppers who associate the manufacturer name with quality or status, think Häagen-Dazs versus a supermarket's own ice cream line.
Consolidation. Some manufacturers merge or acquire to regain scale and negotiating weight against increasingly powerful retail buyers. This is part of why FMCG has seen sustained consolidation among branded players over recent decades.
Selective supply. Some manufacturers refuse to also produce private label for retailers (to protect brand exclusivity), while others willingly become co-packers for private label lines, accepting lower margins for guaranteed volume. This is a real strategic fork every major manufacturer faces.

Private label growth intersects with competition law in specific ways. Regulators including the European Commission and the UK's Competition and Markets Authority (CMA) periodically examine whether large retailers use "buyer power," the ability to dictate terms to suppliers because of purchasing scale, in ways that harm smaller suppliers or ultimately consumers.
The UK's Groceries Supply Code of Practice (GSCOP), enforced by the Groceries Code Adjudicator (GCA), specifically regulates how large UK grocers must treat suppliers, covering issues like payment terms and delisting practices. This exists precisely because retailer power over suppliers, private label being one expression of it, was judged significant enough to warrant a dedicated regulator.
