What should I compare between guest checkout and using an account?

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.

What should I clarify when I need a purchase by a particular date?

Distinguish an estimate from a date explicitly confirmed under stated conditions. Look for separate timing attached to optional additions or customization.

What should I check before buying this product for someone else?

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.
