Potentially problematicWeekend saving

Weekend saving. An unsubstantiated former price makes the current price appear exceptional.. Displayed amount: $180. $79

Neutral alternativeCurrent price

Current price. The product is $79; any comparison states its verified basis and period.. Displayed amount: $79. Was $180 · now $79. Price, period and commitment, expanded: The price and material terms associated with “$79” remain beside this choice.

Why the first version can mislead: The presentation changes what the user can notice or predict at the pricing decision. The problematic state shows: “An unsubstantiated former price makes the current price appear exceptional.” Its influence should be tested by comparing the consequence and usability of “Was $180 · now $79” with “$79”. The reference can create an unsupported impression of exceptional savings and rush comparison.

What a fairer design does: Use a substantiated comparison basis, identify the period or comparator and remove savings claims that cannot be evidenced.

Complete practice context

How this example relates to Misleading reference pricing

A comparison or prior price creates an inaccurate or insufficiently explained impression of savings. 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.
