What this guide covers
Choose what should happen when live campaign windows and directly targeted products overlap.
Pick a policy
Run one campaign alone, let the greater total savings win, choose a priority winner, or allow campaigns to act on separate lines.
Use priority when you want control
The merchant-facing winner choice writes the underlying 0–1000 priority. Diagnostics also exposes the numeric override.
Understand the admin scan
The conflicts page explains detected direct-target overlaps. Its admin scan does not expand collection membership, while checkout still applies deterministic conflict rules to actual candidates.
