The mechanism. On May 8, 2026, USDA's Food and Nutrition Service finalized a rule (effective July 7, enforced by November 4) that more than doubles SNAP retailers' stocking requirements — seven distinct varieties across each of four staple-food categories, up from three, with junk-adjacent items like jerky, cheese dip, and snack bars stripped from the "staple food" count entirely. USDA's own regulatory impact analysis estimates roughly 5,000 retailers — mostly small groceries, convenience stores, and dollar-format outlets with thin produce and dairy sections — could lose SNAP authorization, up from about 2,000 under prior rules. That's not a rounding error; it's a federally mandated culling of the bottom of the retail food chain in exactly the rural and food-desert census tracts where SNAP redemption is concentrated. When a corner store or gas-station grocer gets bounced from the program, the benefit dollars don't vanish — they follow the recipient to whichever nearby store still qualifies. In food deserts, that's almost never a warehouse club. It's the supercenter or the dollar store that already built a full grocery aisle to compete for exactly this customer.
