What’s the difference between registering for an account and guest checkout?

During the checkout process, you’ll be given the chance to register, sign in or checkout as a guest. If you have an account, you’ll have lots more visibility of your orders and there’s the additional ability to cancel an order too, as long as it’s not already being processed. To cancel orders placed with PayPal where a refund is needed, please Contact Us for assistance. 

Guests need to give their name, email address, billing and delivery address, and card details but they won’t create an account, which means that they won't be able to view their orders or receive marketing emails.
