Lead: In December at a Walmart south of Savannah, NPR found that prices on a basket of 114 regularly bought items shifted noticeably over the past year. Shoppers like Greg Reyes — whose household runs on a fixed income — report paying roughly $40 a year ago versus about $60 today for the same groceries, and have cut treats like ice cream. Federal data show U.S. consumer prices rose 2.7% year-over-year in December, but NPR’s basket rose about 5% on average, with tariffs and extreme weather cited as major drivers of some increases.
Key takeaways
- Sample size: NPR re-priced 114 items at one suburban Walmart in Liberty County, Ga., using price-per-unit to control for package-size changes.
- Average change: The basket rose roughly 5% in 2025 versus the prior year, higher than the 2.7% year-over-year CPI increase reported for December.
- Winners (more expensive): Nearly half the items were pricier, including Maxwell House ground coffee (+46%), K-Cup coffee (+34%), shrimp, Oreos, Coca-Cola and Dove soap.
- Losers (cheaper): Just under one-quarter of items fell in price — notable declines included eggs (-30%) and butter (~-16%), after earlier supply shocks eased.
- Tariff signals: Large jumps appeared on goods made in China and Vietnam — e.g., store-brand paper folders (+46%), swai fish fillets (+34%) and some kitchenware (+19%).
- Climate effects: Coffee, cacao (chocolate) and beef showed steep increases tied to droughts, floods and poor harvests, with ground beef up about 30%.
- Shrinkflation: Some products have reduced fill sizes over the past years; NPR observed Tide bottle sizes fall from 100 oz pre-pandemic to 80 oz in December while labeling still claims 64 loads.
- Retail response: Walmart increased discounts (“rollbacks”), reporting more promotions in 2025 and about 2,000 permanent price cuts among roughly 13,000 rollbacks cited for the first three quarters.
Background
Inflationary pressure in the U.S. has moderated from the highs seen earlier in the decade, but prices remain uneven across categories. The Bureau of Labor Statistics reported a 2.7% year-over-year rise in consumer prices for December, reflecting a slowdown from prior peaks yet still straining household budgets. Overlapping forces — a new round of broad tariffs announced by the presidential administration, supply-chain disruptions, and intensifying climate impacts — have created distinct winners and losers on supermarket shelves.
Walmart, as the nation’s largest retailer, is a useful bellwether because of its scale and buying power; it can negotiate prices with suppliers and also decide which items to promote or mark down. Since 2018, NPR has revisited the same suburban Walmart to track price changes over time, standardizing comparisons by price per unit to account for package-size shifts and other labeling differences. That longitudinal view helps separate one-off sales from structural price movement tied to policy, weather or supply changes.
Main event
During the December visit in Liberty County, Ga., NPR recorded the shelf prices and compared them to the prior year. The overall basket rose about 5%, with particular spikes in categories linked to imports and agricultural commodities. For example, Maxwell House ground Colombian coffee rose about 46% and K-Cup varieties rose about 34%, while Hershey’s and Lindt chocolates climbed roughly 26% — movements that retailers and manufacturers linked to tighter raw-material supplies and higher input costs.
Tariffs were a visible thread in the store’s assortment. Items produced or long-sourced from China and Southeast Asia showed some of the steepest increases: a Walmart store-brand paper folder up 46%, swai fish fillets from Vietnam up 34%, and several small kitchen items up between 18% and 19%. Some companies and Walmart told NPR that retailers ultimately set shelf prices, while a few manufacturers pointed to tariffs and higher global costs as contributors behind supply-cost pressure.
Weather-driven shortages amplified price moves for certain staples. U.S. beef supplies are at decades-low levels amid drought conditions, pushing ground beef prices up roughly 30% in this store. Cacao-producing regions in West Africa have suffered multiple poor harvests, contributing to chocolate price jumps; coffee-growing areas have experienced erratic rainfall and heat that lifted bean prices dramatically.
Not all categories rose. Eggs, after spiking earlier because of widespread avian influenza, were down about 30% in December as flock conditions improved. Butter fell nearly 16% amid increased dairy output. Retailers and major brand owners — including PepsiCo and General Mills — signaled targeted price cuts and promotions to defend market share as consumers traded down or skipped nonessential purchases.
Analysis & implications
First, the divergence between the 2.7% CPI and the roughly 5% rise in NPR’s basket shows how headline inflation can mask sharper pocket-level effects. Grocery-staple costs are uneven: items tied to global commodities (coffee, beef, cacao) can surge independently of broader domestic price trends. Low-income shoppers, who spend a larger share of income on food, feel those swings more acutely.
Second, tariffs appear to have a concentrated — if not universally provable — effect. Goods manufactured in countries facing higher U.S. duties exhibited outsized increases in this sample, consistent with firms passing at least some added import costs to retailers or end customers. However, retailers with scale, like Walmart, can sometimes absorb or shift costs through promotional strategies, supplier negotiations, or selective pricing.
Third, climate volatility is a material inflationary channel for food and commodity-linked goods. Recurrent droughts, floods and crop disease in key producing regions have shortened supplies of coffee and cacao and pressured cattle herds, meaning price volatility could persist even if tariffs ease. This creates a policy tension: trade remedies can protect some domestic industries but amplify grocery costs for consumers when major inputs are imported.
Finally, the re-emergence of price cuts and wider promotions signals competitive pressure on big brands. When household affordability becomes the top consumer worry, manufacturers may temporarily reduce prices or increase discounts to retain volume, while supermarkets may shift assortment toward lower-cost private labels. These tactical responses could blunt unit-price inflation but may also compress industry margins.
Comparison & data
| Item (example) | Year-over-year change |
|---|---|
| Maxwell House ground coffee | +46% |
| K-Cup coffee | +34% |
| Ground beef (per lb) | +30% |
| Eggs (dozen) | -30% |
| Reynolds Wrap aluminum foil | +13% |
These sample figures illustrate how commodity-linked items (coffee, beef) and certain imported goods rose much faster than staples like eggs and milk, which fell back after supply shocks. The full 114-item table provides detailed per-unit comparisons and was compiled by scanning nearly every aisle and adjusting for package-size differences where needed.
Reactions & quotes
“We remain dedicated to providing our customers Every Day low prices, with the goal of having the lowest price on a basket of goods over time.”
Walmart spokesperson (retailer statement)
Walmart emphasized its pricing strategy and highlighted the role of promotions and supplier negotiations in managing shelf prices. The company also told reporters it had increased the number of rollbacks in 2025 as part of efforts to soften price pressures for shoppers.
“The result is superior cleaning performance in a smaller dose.”
Procter & Gamble representative (on Tide changes)
Procter & Gamble framed reduced bottle sizes and formula changes as product improvements that allow lower dosing, rather than an attempt to mask price increases — a common industry explanation for observed shrinkflation.
“I used to pay like $40 a year ago, and now we’re paying like $60.”
Greg Reyes (Walmart shopper, Liberty County)
Local shoppers described concrete budget impacts: the same routine grocery trip that cost about $40 a year earlier rose to roughly $60, prompting choices to drop nonessentials like ice cream.
Unconfirmed
- Direct causation between any single price increase and a specific tariff: some price rises align with tariff exposure, but retailers and manufacturers do not always provide item-level cost breakdowns to confirm direct causation.
- Exact degree to which Walmart absorbed versus passed through tariff or input-cost increases: company statements note mitigation but do not disclose detailed margin data at the item level.
- Extent to which product formula changes (e.g., Tide) are solely efficiency improvements versus mechanisms to offset higher input costs; manufacturers assert performance or formulation reasons but independent testing data are limited in the public record.
Bottom line
NPR’s December price check at one Walmart shows that household grocery costs can diverge significantly from headline CPI: a roughly 5% rise across 114 items versus a 2.7% year-over-year CPI reading. The largest upward moves clustered in categories exposed to global commodity shortages and goods imported from countries facing higher U.S. duties; conversely, some supply-recovered categories like eggs and butter fell sharply.
For consumers on fixed or limited incomes, these micro-level swings matter more than aggregate measures. Policymakers weighing trade and climate-related responses should consider how tariffs and extreme weather transmit to food and household product prices. For shoppers, the near-term outlook suggests continued volatility in commodity-linked categories and more aggressive promotions and private-label positioning from large retailers seeking to retain price-sensitive customers.
