Sale timer resets on reload
A fictional retailer shows a fifteen-minute sale countdown that returns to fifteen minutes whenever the page reloads and the price never changes at zero.
Sale ends in. The timer restarts and has no effect on price or availability.. Displayed time: 14:59. Expiry consequence, collapsed
Offer ends at 18:00 CET. The deadline is fixed and the stated discount ends at that time.. Displayed time: 42 minutes remaining. Expiry consequence, expanded: The expiry event and resulting reservation or offer state are shown with the timer.. View the source and period for “42 minutes remaining”
Why the first version can mislead: The message applies immediate pressure at the pricing decision. The cue “14:59” should correspond to a defined operating state and a real consequence. The example instead states: “The timer restarts and has no effect on price or availability.” The timer can manufacture urgency without a corresponding offer deadline.
What a fairer design does: Use a countdown only for a genuine deadline and explain exactly what changes when it reaches zero.

Potentially problematic version
- The timer restarts and has no effect on price or availability.Why this state matters: The message applies immediate pressure at the pricing decision. The cue “14:59” should correspond to a defined operating state and a real consequence. The example instead states: “The timer restarts and has no effect on price or availability.” The timer can manufacture urgency without a corresponding offer deadline.
- Expiry consequence, collapsedReview prompt: Which timestamped inventory, reservation, demand or offer event substantiates “14:59”, and what changes when its limit is reached?
Neutral alternative
- The deadline is fixed and the stated discount ends at that time.Fairer design: Use a countdown only for a genuine deadline and explain exactly what changes when it reaches zero.
- View the source and period for “42 minutes remaining”Review prompt: Record the claim, timestamp, data source and post-claim state; which evidence supports “A decreasing time representation is shown near a choice”?

- Record the claim, timestamp, data source and post-claim state; which evidence supports “A decreasing time representation is shown near a choice”?
- What happens when the stated limit is reached, and could the observed message be the legitimate case “Purely informational clock”?
Complete practice context
How this example relates to Countdown timer
A visible countdown applies time pressure, particularly where it resets, is personalised without disclosure or has no corresponding consequence at zero. This is a design and research taxonomy for learning and evidence review, not a statutory offence label or an automatic finding that an interface is unlawful.
The full guide explains inclusion and exclusion criteria, potential harms, fairer design, evidence questions and separate Australian legal information layers. The example page isolates one scenario so it can be shared and discussed without reproducing the complete library on one page.
