Dollar General is adding audio to 6,000 more stores by July and screens to none of them. DG Media Network, its $170 million advertising arm, declined the screens because the stores cannot fit them. That refusal is the first honest audit the retail media orthodoxy has received.

The orthodoxy rests on one assumption: in-store screens are loss leaders whose capex amortises through advertising revenue. eMarketer puts 2026 US retail media at $71.67 billion, of which in-store accounts for $0.58 billion. The category is asking retailers to front the hardware against a slice under one percent of the whole. The arithmetic assumes a retailer with margin to lend.

Dollar General is not that retailer. Net margin in 2025 was 3.54 percent. On any reasonable estimate, a fleet-scale digital install runs into the tens of millions before a single ad clears, and that is before accounting for the programming and refresh costs that follow.

That is arithmetic, not caution.

Austin Leonard, vp and general manager of DG Media Network, gave Modern Retail the polite version: “Because of the format of our stores, we don’t have a lot of extra space to put screens up.” The impolite version is that a store running 3.54 percent margin cannot carry a screen — not even when advertisers volunteer to pay for it. Power runs and refresh cycles consume advertising revenue faster than the category generates it, on most CFO planning horizons.

Chris Walton, president and CEO of Omni Talk Retail and a former Target executive, noted in the same piece that screens require power wired throughout the store, and that audio is “much, much less expensive.” Retail media’s vendors have spent three years pretending the comparison is obsolete. Dollar General has made it news.

A low-margin retailer choosing the cheap option is unsurprising. The surprise is that the category’s central justification (that advertising amortises the hardware) holds only in stores with enough margin to front it. Retail media has been sorting itself into two tiers: retailers who can underwrite the screens and retailers who must make the network pay from day one. Speakers do both.

eMarketer has long reported that capex and customer experience are why retailers stall on in-store media. The same research does not vindicate the stall; it warns that retailers who wait too long cede ground to Amazon, which carries no such capex constraint and has every incentive to colonise the in-store channel while traditional retailers deliberate. Dollar General has not settled this for its remaining eight thousand stores — Leonard declined to comment on future screen plans — so the decision is tidier in the press release than in the field.

Retail media remains a growth story. It is also, now, a story about which retailers can afford to participate on the industry’s preferred terms. Dollar General has declined those terms because it can count. Whether counting correctly is the same as choosing wisely is what the next eight thousand stores will tell.
