Do you have an Ebay account? If not, you will need to register first. Once registered, purchase the Club Penguin invitation you would like. The seller will have instructions on what information they need from you for the personalization. Generally, the personalization info is sent with your paypal payment in the 'note to seller' section. Most sellers will send you a proof of the invite before it is printed and shipped. I hope this helps. Any other questions, let me know!
