An unexpected seller on a product page calls for evidence about the offer and product. Start by separating an unwanted seller from a specific suspected violation.
Record the offer
Capture the dated public link, marketplace, ASIN, seller shown, condition, price and any product statement that appears inconsistent. Keep screenshots and notes tied to the selected offer rather than the product page in general.

Identify the actual concern
Possible concerns need different evidence. A suspected counterfeit needs evidence about the item. Incorrect condition or a mismatch with the described product needs specific details. An intellectual-property concern needs the relevant rights and a clear description of the suspected infringement.

Prepare an evidence file
Keep the rights or policy basis, affected offer links, supporting material and the question being raised. If the evidence does not support the concern, record what is missing before filing a report.
Retain the report reference and Amazon’s response. Account work can organize the evidence and follow the case; the response and any action remain Amazon’s decision.
