Grocery and retail shoppers in Michigan may be entitled to up to $250 in compensation if they’ve ever been overcharged at the checkout. The lesser-known Scanner Law, officially called the Shopping Reform and Modernization Act, protects consumers when an item scans for more than the advertised price.
How the Scanner Law protects consumers
Enacted in 2011, the law requires stores to clearly display the prices of most products. This can be achieved through shelf tags, electronic labels, or price stickers. If a product scans at a higher price than advertised, consumers are entitled to the price difference plus a bonus of ten times the difference, though the bonus is capped at $5 per item. For instance, if a product is marked $4.69 but scans at $4.89, the shopper would be owed $2.20—the $0.20 difference plus a $2 bonus.
Consumers can claim the difference for multiple items, but the bonus only applies to a single unit. If the retailer refuses to pay, shoppers can pursue the case in court, potentially receiving up to $250 in damages along with a maximum of $300 for attorney fees. To make a claim, shoppers must notify the seller within 30 days of purchase, present their receipt, and allow the retailer two days to respond.

Limits and exclusions of the Scanner Law
While the Scanner Law covers most packaged goods, there are notable exceptions. Items sold by weight or volume, such as bulk produce, prepared foods intended for immediate consumption, or other unpackaged products, are not eligible for the bonus. Shoppers overcharged on these items are still entitled to the price difference but cannot claim the bonus.
The law also applies only to certain types of retail establishments in Michigan. Shoppers should check receipts carefully and confirm the pricing labels match the scanned amounts. Many consumers overlook this step, missing opportunities for compensation.
How to report violations
If a retailer does not comply with the Scanner Law, consumers can report the business to the Michigan Department of Agriculture and Rural Development at 517-655-8202 or 800-632-3835. Complaints can also be submitted in writing to the Weights and Measures section at the EC Heffron Laboratory in Williamston, Michigan. Taking action not only helps recover personal overcharges but also encourages retailers to maintain accurate pricing for all customers.
Being overcharged is a surprisingly common experience, yet many shoppers are unaware that Michigan law provides a straightforward path to recoup losses. By understanding and utilizing the Scanner Law, consumers can recover both the price difference and a bonus, ensuring they are fairly treated at checkout. Vigilance and timely action are key to making the most of these protections.
