What information should I provide when placing an order?
Do not assume every type of purchase requires the same information. Provide account credentials only through the appropriate secure sign-in process, not ordinary seller messages.
What should I check before selecting boxes during checkout?
Consider whether a choice applies only to this purchase. Check whether a required condition applies to your selected product.
What should I check if I cannot find an order confirmation?
Distinguish promotional messages from an actual order acknowledgment. If no order exists, confirm that result before making a fresh attempt.
