As of October 29, 2026, Acosta Group's latest Affordability Tracker shows the share of shoppers who feel comfortable affording groceries and household essentials fell from 68 percent in January to 53 percent in August, a 15-point decline, even as grocery purchasing power improved slightly. For retailers and brands, that gap is the story: the math got marginally better, but the feeling did not, and feeling is what drives where people shop and what they put in the basket.
Purchasing power versus price perception
The numbers behind the mood are modest. For the four weeks ending September 5, Acosta's Typical Stock-Up Trip, an 84-item basket of common grocery and household essentials, cost 366.42 dollars, up 3.5 percent year over year and about 31 percent more than in the comparable 2020 period. Median hourly earnings rose roughly 4.6 percent in the second quarter, which cut the work time needed to buy that basket from 11.84 hours to 11.72 hours, a gain of about seven minutes.
Seven minutes is the entire improvement. Meanwhile the share of shoppers who feel uncomfortable affording groceries and household essentials rose from 17 percent in January to 26 percent in August. That is the definition of an affordability recovery that has stalled: purchasing power is steady, but the cushion households remember is gone, so every trip still feels like a trade-off.
Where the price gap shows up first
Store brands absorb the switch
Over the previous six months, 43 percent of shoppers cut back on nonessentials and 43 percent spent more time looking for deals, while 38 percent bought more store brands and 35 percent shopped at stores with lower prices. The store brand number is the one to watch: it converts a price perception problem into a mix problem, and mix shifts are harder to reverse than a single promotion.
Promotions must be legible, not just deep
Acosta's read is that retailers should make pricing, promotions and assortment easier to navigate, and that brands should communicate the quality and benefits that justify a purchase, with value extending beyond the lowest price to convenience, package size and confidence the product will meet household needs. Depth without legibility just trains shoppers to wait.
What price governance looks like now
The policy environment moved in the same direction this week. On October 26, the National Grocers Association board approved an industry statement on pricing technology covering electronic shelf labels, loyalty programs, artificial intelligence and customer data, organized around four values: treating customers fairly, sharing savings, transparency and protecting privacy.
| Signal | Evidence | Operational response |
|---|---|---|
| Basket cost pressure | 366.42 dollars, up 3.5 percent year over year | Track price gap by category, not just basket average |
| Deal-seeking behavior | 43 percent spent more time looking for deals | Make promotions easy to compare at shelf |
| Store brand shift | 38 percent bought more store brands | Protect the entry price point in each tier |
| Pricing technology rules | NGA statement approved October 26 | No personalized pricing from personal data |
The table works as a monitoring frame rather than a forecast. The first three rows are behavioral and can be measured weekly from loyalty and basket data; the fourth row is a compliance constraint that should be written into how shelf labels and loyalty offers are configured. A price monitoring routine that ignores the fourth row risks a promotion that is legal on paper and hostile in practice.
Building a weekly price review
Price governance fails when it is treated as a quarterly audit, because shopper perception moves weekly while audits move quarterly. The five steps below turn the review into a weekly routine with named owners and retained evidence. The output is a log, not a slide, so that a price gap can be traced back to a specific shelf and date.
The value of the routine is comparability. Acosta's finding is not that prices are high in absolute terms, but that shoppers no longer trust that the shelf price is the best available price. A weekly, item-level log is the cheapest way to test whether that trust is being rebuilt or eroded.
