Anchor Price
The anchor price is the "original" or "compare-at" price displayed next to the current price — the $99 next to the $49 that makes $49 feel like a specific deal rather than an arbitrary number. Humans evaluate prices relative to context; the anchor provides the context.
Anchor prices work when the anchor is believable. $99 anchoring $49 works because both numbers sit in a normal range for the category. $499 anchoring $49 on a $20-retail product just reads as dishonest, and FTC enforcement has been tightening on fake reference prices since 2024.
The same logic applies to tiered pricing: a "Premium" tier at a high price makes the "Standard" tier look reasonable. Sometimes the expensive tier isn't meant to sell — it's meant to anchor the tier next to it.
