How to read Walmart and Kroger clearance tags and digital shelf labels
How to read Walmart and Kroger clearance tags and digital shelf labels (ESLs). What Walmart and Kroger have said, what shopper guides report, and what one enacted state law covers.
Paper clearance tags and digital shelf labels (also called electronic shelf labels, or ESLs) both show the shelf price. This guide sticks to what Walmart, Kroger and one enacted state law have said, with the date we checked each source. It does not treat shopper decoder charts as store policy.
What's a digital shelf label, and what it isn't
Walmart's March 2, 2026 corporate news page calls them digital shelf labels, or DSLs, and describes them as a replacement for paper shelf tags. Associates used to walk the aisles swapping paper tags by hand; now they "manage planned price changes through a centralized Walmart system." Walmart says "DSLs simply modernize how prices are displayed at the shelf."
Kroger, in a January 7, 2019 investor-relations release, describes EDGE Shelf (Enhanced Display for Grocery Environment) as "a shelving system that uses digital displays, instead of traditional paper tags, to indicate everything from prices and promotions to nutritional and dietary information."
Shoppers also search for "electronic shelf labels" or ESLs. We use those names for the same kind of digital price display. The sources below say who sets the price and how it is shown. They do not make the label itself the pricing policy.
What Walmart says about its digital shelf labels
On March 2, 2026, Walmart wrote that "roughly 2,300 Walmart U.S. locations are already using digital shelf labels," and that it expects "this technology to be chain-wide within the next year." Checked Nov 12, 2026.
The same page says price updates "are still people led" and support Walmart's Everyday Low Price (EDLP) promise: "Associates review and push approved changes through a secure system, typically outside of shopping hours, so prices remain stable and consistent during the day." It also says "prices are the same for all customers in any given store and are consistent regardless of demand, time of day or who is shopping."
Walmart says the labels "operate on a closed system and do not interact with shoppers or collect any information about them," and that "there's nothing like a camera or microphone in them, they just display prices."
On Oct. 5, 2026, in a letter titled "Correcting the Record: We Price Products, Not People," Walmart wrote: "We price products, not people." "Walmart does not and will not use an individual customer's personal information, income, shopping history, urgency or willingness to pay to set an individualized price. We do not engage in dynamic pricing, raising prices in response to a hot afternoon or an approaching snowstorm, for example." On the labels: "Digital shelf labels replace paper tags and allow approved price changes to be displayed more efficiently and consistently. They do not identify customers, nor do they independently set prices." And: "Walmart does not and will not use digital shelf labels for individual or dynamic pricing." Checked Nov 12, 2026.
That is Walmart's stated practice and a stated commitment. It is not a law, and it is not a rule we can apply to other chains.
How to read Walmart clearance and Rollback tags (paper and digital)
Walmart's March 2, 2026 page says every item needs "a clear, accurate shelf price," and that DSLs help keep "shelf prices accurate and aligned with what customers see at checkout." Between new inventory, Rollbacks and markdowns, it says pricing updates can stack up fast. Check the price the register charges, and ask a store associate if the shelf and checkout don't match.
Public sites publish charts of what Walmart yellow-tag price endings supposedly mean. Those charts are not Walmart policy, and the sources do not agree with each other. We do not restate cents codes as fact. For the side-by-side of what's reported versus a myth, see Clearance tag codes: what's reported vs a myth. For finding a system price that hasn't reached a paper tag yet, see how to find Walmart hidden clearance. Also see our Walmart store page and the clearance how-to guides.
What Kroger has officially said about EDGE Shelf
The official Kroger source we use here is a January 7, 2019 investor-relations release about a collaboration with Microsoft. It describes EDGE Shelf as digital displays instead of paper tags, for prices, promotions, and nutritional or dietary information, in a 2019 connected-store pilot (stores in Monroe, Ohio and Redmond, Washington). Checked Nov 12, 2026.
That release does not define Kroger sticker colors, and it does not state a current rule for whether a digital tag can change during shopping hours. We did not find a later official Kroger page for this guide that restates those points, so we do not invent them.
Kroger yellow and reduced tags: what's reported, not official policy
Kroger's official pages cited here do not define yellow, "Reduced," or other colored clearance stickers. Claims about what a Kroger yellow tag means are reported, not Kroger policy. We are not adding a third-party color chart or cents codes for Kroger on this page. For how we treat reported tag claims versus official store rules, see Clearance tag codes: what's reported vs a myth.
Do digital price tags change during the day?
It depends on the retailer's policy, not on the hardware alone. Walmart's March 2, 2026 page says associates review and push approved changes "typically outside of shopping hours, so prices remain stable and consistent during the day," and that prices in a given store are "consistent regardless of demand, time of day or who is shopping." Its Oct. 5, 2026 letter says Walmart does not engage in dynamic pricing and "does not and will not use digital shelf labels for individual or dynamic pricing." That is Walmart's stated practice. It is not a rule we can apply to every chain.
New Jersey's Fair Price Protection Act, described below, is not a general ban on changing a posted price during store hours.
What New Jersey's Fair Price Protection Act says
New Jersey enacted the Fair Price Protection Act on July 23, 2026. The official New Jersey Governor news release, checked Nov 12, 2026, says Governor Mikie Sherrill "signed the Fair Price Protection Act into law." According to that release, the Act "prevents businesses from using personal information—such as online activity, location, purchasing history, or other collected data—to charge different prices for identical products based on what an algorithm predicts a shopper is willing or able to pay." It "prohibits retailers from using personal data to set individualized prices on groceries and other necessities for New Jersey shoppers but does not ban loyalty programs or discounts."
The same release says the law "places a one-year moratorium on the new use of electronic shelf labels while the New Jersey Innovation Authority studies the effects and impact of that technology." It "does not require that stores stop using, repairing, or replacing existing electronic shelf labels."
The Governor's release does not describe a general ban on changing a posted price during store hours. This summary stays with that official release. We are not citing unread bill text or unofficial dates.

Walmart's Oct. 5, 2026 letter, also checked Nov 12, 2026, says it does not engage in dynamic pricing and does not and will not use digital shelf labels for individual or dynamic pricing. That is Walmart's stated practice. It is not a rule we can apply to every chain.
Do Walmart digital shelf labels show a different price to different shoppers?
Walmart says no. Its March 2, 2026 corporate news page, checked Nov 12, 2026, says prices are the same for all customers in any given store, that the labels operate on a closed system and do not collect information about shoppers, and that they do not have a camera or microphone. Its Oct. 5, 2026 letter, also checked Nov 12, 2026, says digital shelf labels do not identify customers, nor do they independently set prices.
What does a yellow tag at Kroger mean?
Kroger's official pages cited on this guide do not define yellow, Reduced, or other colored clearance stickers. Claims about what a Kroger yellow tag means are reported, not Kroger policy. We are not adding a third-party color chart or cents codes for Kroger here. For how we treat reported tag claims versus official store rules, see our guide Clearance Tag Codes: What's Reported vs a Myth. The official Kroger source we do cite is a January 7, 2019 investor-relations release, checked Nov 12, 2026, which describes EDGE Shelf as a digital display for prices, promotions, and nutritional information, in a 2019 pilot.
Do Walmart clearance price endings (the last two cents) tell you the markdown stage?
Not as a confirmed Walmart rule. Shopper sites disagree with each other on what endings such as those on yellow tags mean. This is not Walmart policy, and this page does not restate cents codes as fact. For the side-by-side of what those sites report, see our guide Clearance Tag Codes: What's Reported vs a Myth.
Did New Jersey ban stores from changing digital shelf prices during the day?
No. New Jersey enacted the Fair Price Protection Act on July 23, 2026, according to the official New Jersey Governor news release, checked Nov 12, 2026. That release says the law prevents businesses from using personal information to charge different prices for identical products, and that it places a one-year moratorium on the new use of electronic shelf labels, while existing labels may still be used, repaired, or replaced. The same official page does not describe a general ban on changing a posted price during store hours.
