The WIC program aims to help low income and nutritional at-risk women, infants and children. Though federally funded, each state manages their own WIC program. This includes determining the WIC eligibility requirements, provide benefits, services and determining what foods WIC participants can purchase using their voucher/checks or in some cases, their EBT card, at WIC authorized food stores"
