What should I do when product information is unclear or conflicting?
Ask the seller a focused question about the conflicting detail. Treat an unanswered question as uncertainty rather than implied confirmation.

What should I do if checkout changes my selected option unexpectedly?
Compare the checkout entry with the option you intended to choose. Review the product reference alongside its visible option name.
