What does a verified-purchase label on a review tell me?
Read the review content as well as its badge. Check whether the review concerns your intended product option.

Look for disclosed charges before deciding whether to proceed. Review your payment confirmation for the amount actually recorded.
What should I check if a product's displayed price has changed?
