What are the legal requirements for discount expiration dates?

As an e-commerce business owner, I'm concerned about the legal implications of how I structure and communicate discount expiration dates. I want to ensure that my promotional strategies are not just effective, but also fully compliant with consumer protection laws. What specific legal requirements must I follow when creating time-limited offers to avoid potential litigation or regulatory penalties? Are there different rules for online versus in-store promotions, and what documentation or disclosure practices do I need to implement?

TL;DR - Quick Answer

Discount expiration dates must be communicated clearly before the customer acts on the offer, and the expiry must be real and enforced. Vague language like 'limited time' without a specific date creates both consumer protection risks and lower conversion - specific dates outperform vague urgency language.

Legal Requirements for Discount Expiration Dates

Discount expiry requirements have both a legal dimension (you must honor the stated end date) and a trust dimension (customers must believe the expiry is real). Both dimensions point toward the same practice: use specific, real, enforced expiry dates.

Legal Expiry Requirements by Market

United States (FTC)Expiry claims must be truthful; fake urgency is deceptiveFTC enforcement; state AG actions
European UnionUrgency claims must be genuine; fake timers violate Unfair Commercial Practices DirectiveNational competition authorities
United KingdomUrgency must be real; CMA has specifically targeted fake countdown timersCMA investigations; civil liability

Legal vs. Illegal Expiry Practices

Legal

  • Specific date and time communicated
  • Code actually stops working at expiry
  • Timer reflects real remaining time
  • Campaign extended with notice to customers

Illegal / High Risk

  • Timer resets when page is refreshed
  • Code continues working after stated expiry
  • Vague "offer ends soon" with no genuine end
  • Perpetual "sale" with no actual deadline

Best Practice Expiry Communication

  • State specific expiry: "Offer expires [Day], [Date] at [Time] [Timezone]"
  • Show countdown timer synchronized with server time (not local browser time)
  • Include expiry in offer creative, email subject line, and T&Cs
  • Ensure code is technically invalidated at that exact time - not just the front-end display removed

Growth Suite Genuine Expiry

Growth Suite's High-Fidelity Countdown Timer is synchronized to the server, and discount codes are deleted server-side at the moment of expiry. There is no gap between what the timer shows and what actually happens - making all expiry claims legally accurate and technically enforced.
