Pricing

Pricing recommendations should be advisory, not blocking.

Rules

• Prefer recently sold listings over active listing prices
• Store the source and retrieval time for every estimate
• Keep manual overrides available for every item
• Fall back to the last known local estimate if the external source fails

Later integration

The first implementation can use a service wrapper for eBay sold comps or another source without coupling the rest of the app to a single marketplace.
