# 43% of retail media buyers underuse in-store placements—grocers leave shelf-edge screens dark *Brands overspend on digital ads while cheaper, higher-intent shelf media sits idle in 50% of stores.* By **Jenny Huang Goodman MPA MSc MHSA, Principal** — The Stash Edge, Hako Shikin LLC.

Separately, almost **half** of grocery retailers say they're not fully deploying their own media infrastructure—digital screens, aisle displays, and cooler door placements sit dark or run house ads instead of paid campaigns. The gap represents a rare arbitrage: shelf-edge media delivers point-of-decision impressions at a fraction of the CPM of Instagram or Google, yet brands consistently underbuy it. The mechanics are straightforward. Retail media networks—Kroger Precision Marketing, Walmart Connect, Target Roundel—sell digital shelf tags, cooler door screens, and endcap video units that fire when a shopper is within arm's reach of the product. A yogurt brand can trigger a screen on the dairy case door the moment someone opens it. A snack company can claim the endcap screen in the chip aisle during afternoon traffic. Unlike a search ad, the customer is already in the store with a cart and intent. The conversion path is six feet, not six clicks. The mechanism works because it collapses consideration time. Digital shelf-edge screens and cooler door placements sit at the final moment of the purchase funnel—the shopper has navigated to the category, is comparing SKUs, and will decide in the next thirty seconds. A screen showing a recipe, a discount code, or a product callout shifts the grab. According to Supermarket News, grocers report that when shelf media is activated, it typically drives double-digit lift in unit velocity for the featured SKU within the same week. The cost per impression runs **$8 to $15 CPM** depending on the retailer and screen placement, well under social or search. Yet buyers underspend for two reasons: procurement inertia and attribution fog. Brand teams allocate budgets in January around proven channels—Meta, Google, Amazon Sponsored Products. Retail media networks are newer, with less mature dashboards and spottier closed-loop reporting. Even when a brand knows the screen works, the IO often sits with a different budget holder than digital or trade spend. The result: screens go unsold, grocers run house ads for their loyalty programs, and brands overpay for top-of-funnel awareness while leaving the bottom of the funnel unmonetized. The steal for a small physical-product brand is to test one retailer's in-store network with a narrow geographic buy. Start with a **$2,500** pilot: pick one retail chain (Kroger, Albertsons, Whole Foods), one region (three to five stores), and one high-velocity SKU. Buy shelf-edge screens or cooler door placements for four weeks. Run a simple creative—product shot, one benefit line, price. Track scanned unit sales by store using the retailer's portal or your distributor's data. Compare lift versus control stores in the same market. If you see a **15-20%** unit lift, scale to more stores and rotate creative monthly. If attribution is weak, negotiate a test-and-learn deal where you pay only on documented lift—several networks now offer that structure to convert hesitant brands. The broader pattern is that physical retail has digitized faster than brand buyers have. Screens are everywhere—shelf edges, freezer doors, checkout lanes, parking lot kiosks—but the media is still priced like a novelty because demand lags supply. Brands that move budget from saturated digital channels into in-store networks capture cheaper impressions at higher intent, often with same-week sales lift. ## The takeaway Shelf-edge screens cost half of social CPMs, convert at the grab, and sit unsold in half of grocery stores. --- ## Publisher **Hako Shikin LLC** — Virginia Beach, Virginia.
