What should I review when checkout fills in my details automatically?
Read the filled fields instead of assuming they are current. Review the final order summary rather than relying on the initial page.
What information should I check about a seller before purchasing?
Check the stated support route before you need to use it. Check whether the final order record identifies who is providing the purchase.
What does a verified-purchase label on a review tell me?
Check whether the review concerns your intended product option. Do not substitute a badge for checking essential purchase requirements.
