Look for any differences in accessing instructions or order updates. A buyer account and a recipient's access may serve different purposes, so clarify the arrangement when needed.
Distinguish an estimate from a date explicitly confirmed under stated conditions. Look for separate timing attached to optional additions or customization.
Do not assume that access or ownership can always be transferred after ordering. Avoid relying on a past preference if the recipient's circumstances may have changed.
