Village Code requires Oak Park retail stores of 5,000 square feet or greater to charge customers 10 cents for each single-use paper or plastic bag provided at the checkout counter. The program is intended to encourage customers to bring their own shopping bags to avoid taking a single-use, disposable bag that may end up as litter. The local ordinance went into effect in 2018 and was amended in 2023 to include an exemption from the fee for any persons participating in a governmental food assistance program such as LINK, SNAP and WIC. Reusable bags are always available free of charge in the lobby at Village Hall, 123 Madison St.
