Exchange/Return Notes

What should I check before ordering a product again?

Consider whether your own requirements have changed since the earlier order. Review the final selection after using any saved-order shortcut.

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

Do not assume every platform applies the same verification process. Look for any disclosure that affects the context of the review.

How can I assess a product that has few or no reviews?

Consider whether the available evidence is sufficient for your needs. Do not let a short promotional deadline replace necessary verification.
