Every fast food promotion you have ever peeled a sticker off, scanned a cup for, or typed a code into is a legally binding contract. The commercial is not the contract. The poster in the window is not the contract. The official rules document — the one nobody opens — is the contract.
And here is the uncomfortable part: those rules are written by lawyers whose entire job is to make sure the company can give away as few prizes as possible while still saying the word free loudly enough to sell fries. Understanding the mechanics does not make you a cheater. It makes you someone who read the paperwork.
The Ads Are Marketing. The Official Rules Are the Contract.
Almost every promotion includes a line that says something like: In the event of any conflict between promotional materials and these official rules, the official rules govern. That sentence is the entire game. It means anything promised in an ad, a tweet, or a cashier’s opinion is void the second it contradicts the fine print.
In practice, that gives the promoter four levers:
- Eligibility — who is even allowed to win.
- Odds — which are never stated as a number, only as dependent on the number of entries received.
- Prize definition — including the value, the substitution rights, and the expiry.
- Dispute resolution — how you are allowed to complain, and where.
If you only ever read one part of a rules document, read the sections covering those four things. Everything else is decoration.
No Purchase Necessary Is a Legal Requirement, Not a Kindness
That phrase exists because promotions that require payment to enter start looking like illegal lotteries in most jurisdictions. To stay on the right side of the line, promoters have to offer a free alternative method of entry. It is usually buried near the bottom, and it is almost always a mail-in option.
What that free route typically looks like:
- Hand-print your name, address, phone, and email on a piece of paper.
- Mail it to a specific address — often a fulfillment house, not the restaurant.
- One entry per envelope, one envelope per day, postmarked inside the promotional window.
- Entries must arrive before a stated date, which is usually a week or two after the promo ends.
Yes, it works. No, almost nobody does it. The people who do are the ones who figured out that ten stamped envelopes have the same legal weight as ten receipts — often better odds, since far fewer people bother.
You can also just ask for the rules
Most rules documents include a mail or email address where you can request a printed copy of the official rules, sometimes even a winners list after the fact. Requesting the winners list is the fastest way to find out whether a promotion was actually run or quietly shelved.
Eligibility: The Quiet Disqualifiers
Eligibility sections knock out far more people than most entrants realize. Standard exclusions include:
- Employees and their households — usually anyone living in the same home, plus immediate family, regardless of where they work.
- Contractors, franchise staff, and agencies — often written in as an afterthought, but it counts.
- Age minimums — frequently higher than the age required to buy the food.
- Residency and jurisdiction limits — some promos are void in specific territories entirely.
- One entry per person, per household, per device — and yes, they check.
- Account verification — an app account with a fake name or a disposable number can void a win months later.
The household rule catches people constantly. If your roommate works at a participating location, every entry under that address is potentially dead on arrival.
Prizes, Stated Value, and the Tax Bill Nobody Budgets For
Prizes are usually described with an approximate retail value. That number is not what the promoter paid. It is a figure set for accounting and tax purposes, and it is often inflated — a package with a stated value of several thousand might cost the promoter a fraction of that.
Three things matter here:
- You owe tax on the stated value, not the real value. Winning a trip can mean owing money on paper before you have spent a dollar.
- Large prizes trigger paperwork. Expect to hand over identification and tax details, and expect a form filed with tax authorities.
- Substitutions are permitted. Nearly every rules document reserves the right to swap a prize for something of comparable or equal value — a phrase that gives them enormous latitude.
Claiming: The Deadline Is the Whole Game
Winning is not the same as claiming. The claim process is where prizes go unclaimed, and unclaimed prizes are the promoter’s favorite outcome.
- Notification — often a single email, call, or in-app message. Check spam.
- Response window — commonly a few days to a couple of weeks. Miss it and you are disqualified with no appeal.
- Affidavit of eligibility and liability release — a notarized document confirming you qualify and promising not to sue.
- Identity and tax verification — required before anything ships.
- Forfeiture and re-draw — if you fail any step, the prize goes to an alternate.
Prizes are almost always non-transferable, which means you cannot sell your win to someone else and have them claim it. Some rules do allow transferring a physical prize after receipt, but that is a gray area, not a right.
The Clause That Removes Your Right to Sue
Most modern promotions bury an arbitration agreement and a class action waiver in the rules. That means disputes go to a private arbitrator instead of a courtroom, and you cannot join with other entrants.
The detail people miss: some rules include an opt-out window. You send a written notice — email or mail, usually within a set number of days of entering — stating that you decline arbitration. It costs nothing, and it preserves your options if the promoter later refuses to pay.
Codes, Receipts, and App-Only Promos
Digital promotions add their own traps: codes that expire before the promo ends, codes that only work once per account, prizes limited to while supplies last, and app-only entry that quietly locks out everyone without a smartphone. Keep the physical receipt. In a dispute, a receipt is the only proof that survives.
Quietly Legal Workarounds
- Open the official rules before you enter and save the document. Links vanish after promos end.
- Screenshot the promo page at the moment you enter, with the date visible.
- Use a dedicated email address for promotions so nothing gets lost in spam.
- Calendar the claim deadline the moment you enter, not the moment you win.
- Enter through the mail-in route when the odds matter.
- If arbitration is included, send the opt-out notice in writing and keep a copy.
- Log everything — dates, codes, screenshots — in one place before you need it.
When a Promoter Stalls or Refuses to Pay
Start with a written demand that quotes the specific rule section they are violating. That alone resolves a surprising number of cases, because most prize disputes die at the first sign of informed pushback. If it does not, escalation paths generally include consumer protection authorities, promotional regulators in some jurisdictions that require large promotions to be registered or bonded, and small claims courts for lower-value prizes. Arbitration clauses can restrict some of these routes, which is exactly why the opt-out window matters.
Bottom Line
Fast food promotions are not scams, but they are optimized — for participation, for publicity, and for paying out as little as legally possible. The rules that make that happen are public, free, and about a two-minute read if you know which sections to look at.
Read the eligibility list. Note the claim deadline. Save the rules. Use the free entry route if the odds are worth it. None of that is against the rules. It is just playing the game with the lights on.
