What does a verified-purchase label on a review tell me?

Ask for current clarification when older feedback conflicts with the listing. Use verified-purchase information within the broader context of the offer.

What should I check about support if a product is no longer offered for sale?

Describe your specific assistance need rather than asking only about availability. Keep written responses about the assistance available to you.

What should I consider before answering an optional purchase survey?

Keep private order credentials out of free-text response fields. Ask the seller about unclear participation requirements before relying on them.
