What should I review about returns or refunds before purchasing?

If the policy is unavailable, ask for it rather than filling the gap with expectations. Make the purchase with a clear understanding of the applicable process rather than a presumed universal refund policy.

How can I decide whether this product meets my needs?

Think about whether a simpler option would meet the same need. Clarify ambiguous wording before making a decision that depends on it.

What should I verify before marking a support request as resolved?

Do not confuse a proposed action with a completed action. Review the final message for outstanding tasks assigned to you.
