Do retailers have to display prices by law? There is no single federal statute that forces a sticker onto every product, but a combination of federal deceptive-practice rules and roughly 20 state pricing laws means you have a right to know what something costs before you commit to buying it. How that price appears — a tag on the item, a shelf label, or clear signage — depends on where you shop.
What Federal Law Requires
The broadest rule comes from Section 5 of the FTC Act, which makes unfair or deceptive acts or practices in commerce unlawful.1Office of the Law Revision Counsel. 15 USC 45 – Unfair Methods of Competition Unlawful; Prevention by Commission Federal Reserve guidance interpreting Section 5 identifies withholding material price information until after a consumer has committed to a purchase as an example of an unfair practice, and it lists misleading cost or price claims as deception.2Board of Governors of the Federal Reserve System. Federal Trade Commission Act Section 5 – Unfair or Deceptive Acts or Practices A retailer that systematically conceals or misrepresents prices risks FTC enforcement, with civil penalties reaching $53,088 per violation in 2025.3Federal Trade Commission.

What federal law does not do is dictate format. It does not require individual stickers, specific shelf-label sizes, or any particular display method. It requires only that the price be truthful and available to you before you commit. The mechanics are left to the states.
What State Laws Add
According to NIST, roughly 20 states maintain their own retail pricing statutes or regulations, including Alaska, California, Connecticut, Michigan, New Jersey, New York, and Ohio.4National Institute of Standards and Technology. U.S. Retail Pricing Laws and Regulations by State Some of these states require “item pricing,” meaning most individual products must be physically marked with their selling price. Others let retailers rely on clear shelf tags or signage, which fits modern scanner-based systems. If you are trying to figure out what applies where you live, the answer is state-specific and worth checking against your own state’s rule.
Enforcement usually falls to local or county departments of weights and measures. Under the NIST Examination Procedure for Price Verification, a store fails an inspection when more than 2% of sampled item prices differ from what the register charges.5National Institute of Standards and Technology. Price Verification FAQs Passing means at least 98% of displayed prices matched checkout at the time of the audit. That is the benchmark inspectors use nationwide, though individual states may set stricter standards.
Exceptions to Price Display Rules
Even strict item-pricing states carve out categories where individual tagging is impractical. Common exemptions include:
- Bulk items sold by weight, like fresh produce and deli meats displayed loose rather than pre-packaged.
- Very small items, like individual pieces of candy, gum, or small hardware where a sticker would be larger than the product.
- Vending machine products, dispensed by machines the customer operates.
- Custom-ordered goods built or assembled to a buyer’s specifications.
Some jurisdictions also exempt smaller retailers from certain requirements. Revenue thresholds vary, and the reasoning is to spare neighborhood shops the labor cost of tagging every item when clear shelf signage does the same job.
Advertised Sale Prices and Rain Checks
Displayed prices include the ones in weekly circulars and store ads. When a retailer advertises a product at a sale price, federal rules require the store to actually have it available. Under FTC regulations for retail food stores, it is an unfair or deceptive practice to advertise a product at a stated price if covered stores do not have the item in stock during the sale period, unless the ad clearly discloses that supplies are limited or that the product is available only at some locations.6eCFR. Part 424 – Retail Food Store Advertising and Marketing Practices
If the store runs out, it can comply in several ways: show it ordered enough to meet reasonably anticipated demand, offer a rain check letting you buy the item at the sale price once restocked, offer a comparable product at the same discount, or provide other compensation of equal value.6eCFR. Part 424 – Retail Food Store Advertising and Marketing Practices Many states layer their own rain check laws on top, often requiring the rain check to specify the exact item, the sale price, and a deadline for honoring it.
Why the Register Price Is Higher Than the Shelf Price
If the total at checkout is higher than what you saw on the shelf, the cause is almost always sales tax. Across most of the United States, the price on the shelf or tag excludes sales tax, which is calculated and added at the register. That is standard practice, not a violation. Multiple state pricing statutes explicitly define “total price” or “retail price” for labeling purposes as the price excluding sales tax.
The reason is practical. Sales tax rates vary by state, county, and city, so national and regional retailers would face enormous complexity trying to bake location-specific tax into every label. The displayed price is what the retailer charges for the product; the tax is a government-imposed addition collected at the register. A few jurisdictions handle this differently, but tax-exclusive shelf pricing is the overwhelming norm.
Mandatory retailer fees are a different matter. A store that advertises one price and then adds undisclosed mandatory charges at checkout is engaging in the kind of bait-and-switch the FTC has long treated as deceptive under Section 5.2Board of Governors of the Federal Reserve System.

When the Shelf Price and Register Price Disagree
The shelf says $3.99 and the register rings up $4.49. It happens more than it should, and many states have scanner accuracy laws that address it directly. The general rule in these states is simple: when shelf and scanned prices conflict, you pay the lower one.
Some states go further with “scanner bounty” provisions. If the register overcharges, the store owes you not only a refund of the difference but a small bonus on top. These bounties typically range from $1 to $10, depending on the state and the size of the overcharge. Some states cap the bonus, some set a minimum, and most require you to flag the error with your receipt within a set window, often 30 days. Not every state has these provisions, so the protection available depends on where you shop.
For the store itself, the 2% NIST accuracy threshold is the practical standard. Stores below it during an inspection pass; those above it fail and may face enforcement from the local weights and measures office.5National Institute of Standards and Technology. Price Verification FAQs
What to Do About a Pricing Violation
Start at the register. Most pricing errors are genuine mistakes: sales that ended but were not updated in the system, or shelf tags that were never swapped. Point the discrepancy out to a cashier or manager and you will usually get the lower price on the spot. Keep your receipt either way.
If the store will not fix it, escalate to your state attorney general’s consumer protection division or a local consumer protection agency. Many accept complaints online and will investigate patterns of overcharging. Your local department of weights and measures is another option, since those offices run the pricing inspections and have direct enforcement authority over scanner accuracy.
When you file, include the date and time of the transaction, the store name and location, the specific product, the displayed price, the price charged, and a copy of your receipt. A single complaint about one product may not trigger action, but agencies look for patterns. Yours could be the tenth report about the same store, and that is when investigations begin.
