What is PayPal Express?
PayPal Express is a particular type of payment option that can be enabled on your website.
Instead of entering address information onto your website, the customer instead clicks a PayPal Express button on your shopping basket page which directs them straight through to PayPal to login to their account.
Their billing and delivery addresses are set on the PayPal website and only once they complete payment will they be sent back to your website.
It is 'Express' because their address information will already be stored in their PayPal account.
