A checkout summary is the final order screen shown before payment. It typically lists the amount due now, applicable taxes, the product or plan, the billing interval, and any renewal terms. For subscriptions, it helps distinguish a prepaid introductory period from the later renewal charge.
Reviewing this screen is a practical defense against unexpected costs and misleading or unclear offers. Confirm the total, currency, subscription duration, renewal date and price, and cancellation terms before authorizing payment. In attacks involving deceptive checkout pages, criminals may obscure fees, change payment details, or use confusing wording; checking the summary against the offer and using a trusted site can help reduce the risk.
