What should I check before choosing a payment method at checkout?
Do not assume every advertised method works for every product option. Ask about unresolved status before attempting another payment.
What should I review before closing an account that contains purchase records?
Check whether access to a purchased benefit depends on the account. Review whether the requested action is temporary deactivation or permanent closure.
How can I check an existing order's status without submitting another purchase?
Look for the existing order in the purchase channel's order history. Check whether a second record is an amendment rather than a separate purchase.
