What Is a Real Free Sample? The FTC's Rules on the Word "Free"
The word "free" isn't just marketing copy — it's a specific, regulated claim with rules attached. Here's what those rules require, and where a "free sample" commonly stops being one.
A federal rule, not just a marketing word
Long before online freebie sites existed, the Federal Trade Commission wrote a rule specifically about the word "free" in advertising: the "Guide Concerning Use of the Word 'Free' and Similar Representations," codified at 16 CFR Part 251. It applies to "free," "buy one get one free," "half off with the purchase of one at regular price," and similar claims. The practical effect is that "free" isn't a vague, feel-good adjective a seller can use loosely — it's a specific claim the FTC can act on if it turns out to be misleading.
The core rule: no hidden markup, no downgrade
Two requirements do most of the work. First, every condition of a "free" offer — what you have to buy, do, or provide to get it — has to be disclosed clearly and conspicuously at the outset, not revealed after you've already committed. Second, and this is the part sellers most often get wrong: a company can't recover the cost of the "free" item by quietly raising the price of whatever purchase is required alongside it, or by substituting lower-quality goods for what it normally sells. In plain terms, you're supposed to end up paying nothing for the free item and no more than the regular price for anything you're required to buy — if the "regular" price was invented for the occasion, the "free" claim is doing the opposite of what it says.
Why the same "free" deal eventually disappears from an area
The same FTC guide also limits how often a company can run the identical "free" promotion in the same trade area: generally no more than six months' use within any twelve-month period, with at least 30 days between repeat runs, and no more than three such offers in one area per year. That's a limit on how often a company can lean on the same "free" claim in one market — not a per-customer limit, so it doesn't mean you personally can only claim one free sample from a brand ever. It does explain why a "free" promotion that ran constantly for over a year in the same form would be unusual under the rule as written.
Free trials are a different rule entirely
A subscription that starts "free" and later charges you automatically isn't covered by the free-advertising guide above — it falls under separate law aimed at negative-option and free-trial offers. The Restore Online Shoppers' Confidence Act (ROSCA, 15 U.S.C. § 8403) requires a seller to clearly disclose the trial's terms — including that it will convert to a paid subscription and what that will cost — before charging you, and to get your express informed consent to those terms. The FTC also has a broader rule requiring an easy way to cancel such offers (often called "click-to-cancel"), but its 2024 expansion was struck down by a federal appeals court in July 2025, and the FTC reopened that rulemaking in early 2026 — so treat the cancellation mechanics as unsettled and read the actual terms of any "free trial" rather than assuming a specific cancellation method is guaranteed.
What this means for a listing on this site
Translated into a plain checklist: the product itself has to cost $0, a clearly disclosed flat shipping charge is compatible with "free," and a required prepayment, "processing fee," or full-price charge followed by a promised refund is not a free sample under this framework — whatever it's called, it's a purchase or a cashback offer instead. A listing that hides its real terms until after you submit your information reverses the FTC's "disclose it upfront" requirement, not just this site's house standard.
A worked example: "buy one, get one free"
The core rule is easiest to see in a "buy one, get one free" offer, which the FTC's guide specifically covers alongside plain "free" claims. If a product normally sells for $10 and a store runs "buy one, get one free," the math the guide expects is simple: you pay $10 total and walk out with two units — not $12, and not one full-size unit plus one that has quietly shrunk. If the "regular" $10 price only ever appears during the promotion, and the item normally sells for $7 the rest of the year, the "free" half is really a smaller discount wearing a bigger-sounding label — which is exactly the kind of markup the guide is written to prevent.
