Grocery stores cannot markdown perishables fast enough because the pricing decision requires a manager's approval, and by the time they act, the product is unsaleable

A package of ground beef with two days until its sell-by date sits on the shelf at full price. The meat department clerk notices it at 2 PM but cannot change the price -- markdowns require a department manager's approval, and the manager is in a meeting, on break, or covering another department. By the time the markdown sticker goes on at 5 PM, the product has 36 hours left and needs a 50% discount to move. If the clerk had been empowered to mark it down at 10 AM three days earlier with a 20% discount, it would have sold at a higher margin. This pattern repeats across every perishable department in the store, every day. The prepared foods and deli department is the worst offender: 8.33% of total prepared food goes unsold, making it the highest waste category in grocery retail. Rotisserie chickens, prepared salads, and hot bar items made at 10 AM have a 4-hour safe window under hot holding, after which they must be discarded or refrigerated and sold cold at a steep discount. Most stores make these products on a fixed schedule based on historical patterns rather than real-time foot traffic, so a slow Tuesday still gets the same number of rotisserie chickens as a busy Saturday. The problem persists because dynamic pricing in grocery is technically and culturally difficult. Technically, most grocery stores still use paper price tags or simple electronic shelf labels that require manual updates. The few chains experimenting with dynamic pricing (like Wasteless AI) face consumer backlash -- shoppers perceive fluctuating prices as unfair or confusing. Culturally, grocery managers resist early markdowns because they fear "training" customers to wait for discounts. The result is a lose-lose: the store takes a total loss on products that could have been sold at a reduced margin, and consumers who would happily buy discounted near-date products never see them because the markdown happens too late or not at all.
