What is PayPal? 
PayPal is a popular, safe and easy way to pay online. It uses industry-leading
security and fraud prevention systems to protect your financial information.
PayPal receives your financial information, so we never see your credit card or
any other details. Every payment is confirmed with an email receipt and there is
100% protection against unauthorised payments sent from your account. Plus, it
is super speedy, you can pay with your credit card, debit card or bank account,
and once registered there is no need to retype your financial information. For
more information go to PayPal’s website
