Generic “only one left” across every variant
A fictional store displays “Only one left” for every size and colour even though the warning is not linked to variant-level inventory.
This is an original fictional comparison. It depicts no real company and is not a legal finding or safe harbour.
Generic “only one left” across every variant
A fictional store displays “Only one left” for every size and colour even though the warning is not linked to variant-level inventory.
Only one left. The same warning appears for all sizes regardless of stock.. 1 remaining. Claim basis, collapsed
Stock for selected size. The message reflects the chosen variant and current inventory.. Size M · 4 available. Claim basis, expanded: The relevant population, period, inventory or offer state is presented with the message.. View the source and period for “Size M · 4 available”
Why the first version can mislead: The message applies immediate pressure at the pricing decision. The cue “1 remaining” should correspond to a defined operating state and a real consequence. The example instead states: “The same warning appears for all sizes regardless of stock.” A shopper may rush or skip comparison because a broad scarcity claim appears precise.
What a fairer design does: Tie stock messages to the selected item and timestamped inventory, or omit them when the basis is unavailable.

Review questions (3)
- Which timestamped inventory, reservation, demand or offer event substantiates “1 remaining”, and what changes when its limit is reached?
- Record the claim, timestamp, data source and post-claim state; which evidence supports “The claim refers to remaining inventory quantity”?
- What happens when the stated limit is reached, and could the observed message be the legitimate case “High demand without remaining quantity”?

How this example relates to Low-stock claim
A claim that few units remain applies purchase pressure, especially where inventory basis or persistence is unsupported. The label describes a recurring design mechanism; whether a particular implementation is harmful or unlawful depends on the complete journey, audience, evidence and rules within scope.
The full guide explains inclusion and exclusion criteria, harms, fair design principles, evidence questions and the relevant EU legal information layers. The example page isolates one scenario so it can be shared and discussed without reproducing the complete library on one page.
