Aldi’s limited inventory is driving down grocery prices

The American grocery market has long been defined by massive superstores that offer everything from produce to electronics under one roof. That model is now facing pressure from a competitor that does the opposite.

Aldi, a German grocer founded in 1946, aims to operate more than 3,000 locations in the United States by the end of 2028. This expansion would place the chain just behind Walmart in total store count. In 2024, Aldi recorded approximately $29 billion in U.S. sales, surpassing the revenue of Trader Joe’s.

The chain’s strategy relies on two distinct operational choices. First, more than 80 percent of the items on its shelves are private-label products. These are store-brand versions of national items, such as cookies that resemble Oreos, which allows Aldi to avoid paying markups to major manufacturers like Nabisco. Second, the stores stock a strictly limited selection of goods. By carrying only one or two brands of each item, Aldi buys in bulk and reduces spoilage, storage costs, and real estate needs.

This efficiency allows Aldi to match or undercut the prices of larger rivals. Food reporter Deena Shanker noted that over several months of comparison shopping, Aldi consistently priced items at or below Walmart levels. This pressure is already visible in the market. An analysis from late 2023 found that grocery chains reduced their markups by roughly 7 percent in areas where a similar German competitor, Lidl, opened stores. Major U.S. grocers like Kroger and Wegmans have since announced defensive price reductions in response to this trend.

The limited inventory means shoppers often must visit other stores for specific items. Aldi intentionally locates its stores near competitors to facilitate this split shopping. This approach contrasts with the bundling strategy of traditional superstores, which combined various retail categories to capture more customer spending. Aldi has effectively unbundled the grocery experience, focusing only on essentials it can sell at a lower cost.

The chain also maintains a distinct retail atmosphere to retain customers. Stores feature minimal decor and no background music to save on licensing fees. Staff place products on shelves directly from their shipping boxes. While this may seem shabby to some shoppers, it is a deliberate cost-cutting measure. Aldi also offers rotating specialty items, such as German foods and novelty goods, which give the store a unique character that standard big-box retailers do not replicate.
