Sentinel of the Shelf

Enter an item, its MSRP, and the current asking price. The Sentinel will calculate the markup, classify the listing, and return a calm verdict on whether the price is fair, inflated, or completely detached from reality.

Listing Scan Input

Quick rule of thumb: retail or near-retail is good. Mild markup is tolerable. Once the price starts floating away from MSRP like a cursed balloon, the Sentinel notices.

Status Bands
  • 0-10% over MSRP: Fair
  • 11-30% over MSRP: Acceptable
  • 31-75% over MSRP: Inflated
  • 76%+ over MSRP: Absurd

Fairness Drift 0%
This tool compares the current price to MSRP only. It does not verify true rarity, production counts, aftermarket demand, shipping, or condition. It is a fast judgment tool - not an oracle from the abyss.
