A confirmation page is the first page a visitor sees after a conversion and normally will provide details of the order, including the price and delivery time scales. It is also a great time to request something else as customers have just made a commitment to a purchase that they may want to celebrate through social sharing and will be most open to other requests as they seek to reassure themselves they have made a good decision. This means it can be a good time to also ask for personal details to improve your customer profiling or seek a further conversion.
This confirmation page from Amazon uses the opportunity to promote items related to the purchased product, but it also displays personalised recommendations that are not be linked to the conversion.
