A safe and secure shopping environment is very important to us in order to create loyal customers.

You do not need an account to use your credit card with PayPal.

When you pay with PayPal, you shop without sharing your financial information. Plus, PayPal meets the exacting standards of the major card associations, including SAS, PCI, and SDP.
PayPal uses industry standard Secure Sockets Layer 3.0 (SSL) or higher to secure communication sessions. All sensitive information sent between your computer and PayPal servers, is encrypted.
Information is stored on PayPal servers and heavily guarded, both physically and electronically. To further shield your credit card and bank numbers, these firewall-protected servers are not directy connected to the internet.
