Bait and Switch

What it is

Advertising an attractive offer the seller does not intend to fulfil as described, then steering the customer who responds toward a different, less favourable purchase.

How it works

The bait exploits attention and the cost of showing up; the switch exploits what the customer has already invested. Once someone has driven to the lot, filled a cart, or spent an hour comparing, the switch is cheaper than starting over, so sunk cost and commitment do the seller's work. The advertised item is disparaged (“honestly, that model has problems”), declared sold out, or hedged with conditions that were never mentioned (credit tier, quantity, location), and the “real” product is presented as the sensible alternative. The FTC's Guides Against Bait Advertising, first issued in 1959, define the practice as an “alluring but insincere offer” and treat refusing to show, disparaging, or under-stocking the advertised item as evidence of intent; the EU Unfair Commercial Practices Directive lists bait advertising and bait-and-switch among the practices deemed unfair in all circumstances. Digital versions substitute a listing photo for the unit actually supplied, a “deal” that redirects to a pricier near-identical product, or a job advert that turns out to be a recruitment pitch.

Real-world examples

  • •Auto retail: the FTC's 2024 CARS Rule was written largely to stop dealers advertising vehicles and prices they would not honour; the Fifth Circuit vacated it in January 2025 on procedural grounds, leaving the 1959 Bait Advertising Guides and state consumer-protection laws as the main tools.
  • •“Doorbuster” sale items advertised without disclosing that only a handful exist per store, so that the crowd the ad draws is sold something else; several US states require “limited quantities” disclosure for this reason.
  • •Rental and holiday listings that show one unit and deliver another, then offer an “upgrade” at extra cost when the guest arrives with luggage and no alternative.
  • •“Work from home, no experience needed” adverts that resolve into a multi-level-marketing enrolment or a paid “training” package once the applicant has attended the presentation.

Ethical guidelines

  • ●Advertise only what you intend to sell, at the advertised terms, in quantities reasonable for the expected response; disclose limits in the ad itself.
  • ●Never disparage the advertised item or steer toward a substitute; if it is genuinely unavailable, offer a rain check on the same terms.
  • ●Bait advertising and bait-and-switch are per se unfair under EU law and deceptive under the FTC Act; no disclosure in fine print cures a headline the seller never meant.

How to defend against it

  • ►Before travelling or committing time, get the advertised offer confirmed in writing: “Is this exact item available at this price today?” Screenshot the ad with the date.
  • ►When the switch begins, notice the disparagement of the thing you came for — that is the tell — and treat your travel time as already spent. Walking out costs nothing more; buying the substitute costs the difference.
  • ►Verify “sold out” claims independently: call another branch, or check the retailer's own site for stock before accepting the alternative.
  • ►Apply the 24-hour rule to any substitute the seller proposes; a genuine offer will still exist tomorrow.
  • ►Report to the FTC and your state attorney general (US), the ACCC (Australia), the CMA or Trading Standards (UK), or your national consumer authority (EU); bait advertising is one of the most enforceable practices because the advert itself is the evidence.

Upload or paste an image (or a video frame) into an image search engine to find where else and when it has appeared, which exposes recycled photos, stolen profile pictures, and images given a false caption.

Report Dark Patternsminutes

When an interface tricks you (a hidden charge, a fake countdown, a cancellation maze, consent you never gave), document it and report it to the regulator and the platform, because enforcement against deceptive design is driven by complaint data and one documented report protects people who would never have spotted the trick.

Every playbook entry states how strong its evidence is and when not to use it. Browse the full playbook.
