  • System Requirements

    Our goal at costco.com is to create an online shopping experience that is exciting, easy, and secure, from the moment you visit our site to the time you receive your order. To ensure this, there are a couple of system-related topics we need to explain:

    Browser Requirements

    Internet Explorer 4.0 or above, or Netscape 4.0 or above. To place orders at costco.com, you need a browser that supports Secure Sockets Layer (SSL) 128-bit encryption technology. This is required to attempt to keep unauthorized parties from reading the transactional information you send us. If you need to upgrade your browser, you may download free upgrades from either Microsoft or Netscape.
