If an alternative product is involved, confirm its exact option and scope. Avoid agreeing merely because you feel rushed by an unclear message.
Check whether the seller has actually confirmed the order after submission. Avoid assuming availability in one context applies to every customer or option.
Check whether the service sends alerts once or repeatedly. Make a fresh purchase decision using the offer available then.
