Shipping Trap Checker
Spot the shipping that kills the deal.
Detects whether shipping cost will eat the resale margin before you click buy. Three verdicts: Safe Ship, Caution, or Shipping Trap.
Built for the way you actually shop.
Three-tier verdict
Every listing gets Safe Ship, Caution, or Shipping Trap based on weight, dimensions, fragility, and category-specific shipping reality.
Factor-by-factor breakdown
See exactly which factors pushed the verdict where it landed. No hand-waving — the math is on the screen.
Sourcing presets
Parcel-first, balanced, and freight-tolerant presets out of the box. Pick the one that matches how you sell, or tune your own thresholds.
Manual override + storage
When parsing is incomplete, override the dimensions or weight yourself. Overrides persist per listing in extension storage.
Extraction quality indicator
See whether parsing is strong or fallback-heavy on any given listing. Trust the verdict when the indicator is green.
JSON export for handoff
Export the current analysis as JSON for debugging, sharing with a partner, or piping into your own spreadsheet workflow.
