The value grocery segment is experiencing a shift as changing consumer habits and store expansions reshape where and how Americans shop for food.

Location intelligence data from Placer.ai demonstrates that while discount grocers share a core commitment to affordability, their underlying strategies for driving foot traffic vary widely — with key implications for perishable categories like fresh produce.

Distinct Playbooks for Growth

Aldi continues to dominate headlines through sheer physical growth, maintaining its position as the fastest-expanding chain in the grocery sector. According to Placer.ai’s report, “Aldi and Trader Joe’s Take Different Roads to Growth in 2026,” overall visits to Aldi rose between 1.3% and 6.4% year over year each month between January and August. By focusing on a “no-frills value for the basics” model, the retailer has built a steady customer base that relies on its low-cost foundational staples.

By contrast, the same report highlights how Trader Joe’s leverages limited product releases to generate substantial, short-term foot traffic spikes. Surges in summer visits — up 7.7% in June, 12.2% in July and 10.6% in August — were heavily fueled by viral merchandise drops, including its canvas tote bags and insulated mini totes.

Meanwhile, a separate Placer.ai report, “Lidl’s Slow Build is Outpacing Value Grocery Where it Competes,” finds that Lidl’s methodical buildout along the East Coast is outperforming the wider value-grocery segment. The report notes that Lidl posted steady year-over-year visit gains of 4.7% in June, 6.1% in July and 2.8% in August, beating regional market benchmarks.

Fresh Produce Drives Visit Frequency

Behind these macro traffic numbers lies a fundamental evolution in consumer behavior, particularly when it comes to fresh foods. Since the pandemic, shoppers have been visiting stores more frequently and spreading their budgets across a wider variety of retail banners than ever before. Rather than stocking up during one large weekly shop, consumers are making quick, real-time runs to get perishable items as close to the date of consumption as possible.

Produce plays a pivotal role in this shifting rhythm.

“Produce is a key driver of that,” says Nicole Collida, senior vice president, managing director, U.S. retail for NielsenIQ. “As consumers are trying to get the freshest products possible — taking stock of their weekly grocery needs more in real time — that has really driven this behavior. Consumers are making trips based on the retailer’s specialty, but also based on trying to get things as close to the date that they need them as possible.”

This consumer demand for fresh products close to the date of use has benefited value-based chains like Aldi, Lidl and Trader Joe’s while driving parallel growth in fresh-format grocers. It also reflects a growing consumer focus on health and wellness trends.

The Rise of Mission-Driven Shopping

Because limited-assortment retailers typically carry curated or prepackaged produce sections, shoppers are increasingly demonstrating what Placer.ai calls “mission-driven behavior.” Consumers understand the specific strengths of each retail banner and curate their shopping trips accordingly.

“They know the specialty of each retail chain, and they’re choosing that chain for that specific category or for that specific expertise. ... I think that a lot of consumers are choosing Trader Joe’s specifically for the things that they really excel at, and then they are probably then looking to maximize the remainder of their grocery visitation throughout the week with other retailers that might be better served for sort of the fresh product side of things,” Collida says.

This mindset creates high levels of cross-visitation between discount players and conventional supermarkets. While value shoppers enter stores like Aldi or Lidl knowing exactly what to expect, they frequently double-shop at national or regional grocers, big-box stores or local markets to complete their perishables basket.

“Especially with Aldi and Lidl, the consumer who is going there is really focused on the value proposition of those chains, so they walk in knowing exactly what they’re going to get,” Collida says. “For them, it’s figuring out what the best products are to source [from] this retailer, and then where else they need to go to fill in for categories those retailers don’t specialize in.”

Shorter Dwell Times Across the Board

At the same time, overall store dwell times across the grocery category have steadily declined over the past five to six years. Because consumers are making more frequent trips for specific items, the overall in-store process has become much more expedited.

“As consumers try to visit grocery retailers as close to when they need to use those products as possible, the trade-off is that they’re spending less time in-store because they’re only going in for a couple of things,” Collida says. “They know they’re making multiple trips to different chains, they know exactly what they’re looking for and they know where to find it. Across the board, the grocery shopping process has become a lot more expedited.”

Outlook for the Value Segment

Ultimately, the steady rise of value grocers reflects a broader economic reality. As lower- and middle-income consumers become increasingly price-conscious, value chains have expanded their footprints to reach previously underserved markets.

“As consumers across the board — particularly lower- and middle-income shoppers — become much more value-focused, the timing of these retailers continuing to expand their fleets really aligns with where the consumer is right now,” Collida says. “These retailers have stepped up to meet the moment. This is definitely a trend we will continue to see, as these chains have honed in on their value proposition and made themselves a must-visit location in the consumer’s weekly grocery trip.”
