In short
- Losing the buy box on your own product is usually a symptom, not the problem.
- The fastest route back is rarely the legal one.
- Prevention is mostly about who you sell to, not what you say on Amazon.
How do you know it is happening?
The first sign is usually price, not the seller list. If your product is being sold below where you set it, somebody else is setting it.
You cannot enforce your way out of a distribution problem.
What actually gets the listing back?
Brand Registry gives you the tools. Distribution control gives you the outcome. Most brands try the first and skip the second.
