# Unclear pricing signals — dev spec
Site: yahoo.com · Priority 4 · High · Effort: High (5+ days)

## Problem
The homepage displays various prices without context, potentially confusing users about what is being sold and creating hidden cost perceptions.

## Evidence (from the live site)
> Prices on homepage: $4, $149, $75, $1, $66, $28,000
> The homepage body sample shows prices like '$4', '$149', '$75', '$1', '$66', '$28,000' embedded in content, but no clear product or service is associated with them, and there is no pricing page link in the navigation.
