We use PayPal as our Website Payments Processor because it offers a secure method of payment, with both buyer and seller protection.
Clicking the gold "PayPal" button on our Checkout Page will take you straight to the Express Checkout on their secure server. (The address fields will be pre-filled for PayPal members)
If you would rather pay by Debit or Credit Card, simply click on the Visa/Mastercard buttons to complete your purchase by card in the normal way. The PayPal Guest Checkout will open in a new window on their Secure Server. You can choose to simply ignore any prompts to sign up for a PayPal account unless you wish to do so.
If this payment window fails to open, it is most likely because you didn’t complete all the ‘required fields’ on our checkout page. (If you are signed in to your Lavinia Stamps account, the address fields will be filled in automatically)
PayPal is now a highly respected and secure payments processor and is used in this way by millions of businesses worldwide, such as Boots, John Lewis, British Airways and Next. You can shop with confidence. If your purchase doesn’t match the seller’s description, PayPal Buyer Protection can reimburse you. (https://www.paypal.com/uk/webapps/mpp/paypal-safety-and-security
