IL HB2910

Amends the Sale Price Ad Act to require retail mercantile establishments (grocery stores and supermarkets where 55% or more of sales are food, beverages, or nonprescription medicines) to disclose discounted prices in multiple formats, including original and discounted prices, percentage savings, or credit amounts.

Allows retailers to provide discount notices through various channels including point-of-sale displays, receipts, email, text messages, mobile apps, in-store promotions, loyalty programs, or other reasonable means.

Exempts self-service checkout systems and wholesale club membership models from discount disclosure requirements.

Requires that final purchase prices with discounts be excluded from fees charged to retailers by payment processors when consumers use cards, coupons, or similar payment devices.

Makes discount price regulation an exclusive state power, preventing home rule municipalities from enacting local regulations on this matter, and caps fines at $25 per violation with a maximum of $500 per year per entity.
