You may have been shown a browser warning pop-up similar to the one below:

To continue to provide you with the best experience online, Bunnings is adhering to changing web environments and security protocols by removing support of TLS 1.0 from April 2018. TLS, or Transport Layer Security, is required for secure Internet communication.
The Payment Card Industry (PCI) Data Security Standard stipulates that the TLS 1.0 encryption protocol can no longer be used for secure communications. Any web servers which still support TLS 1.0 or below will fail the PCI standards and therefore will not be allowed to take credit card payments online. The PCI DSS standards can be read in full here: https://www.pcisecuritystandards.org/document_library?category=pcidss&document=pci_dss
Bunnings follows the PCI standards to keep our customer’s credit card details secure. Bunnings never collects customers credit card details, and customers must either update their browsers or switch to TLS 1.1 or above to maintain security, ensuring orders can be completed successfully.
What we recommend
We recommend you upgrade your browser to the latest version for security reasons. We advise all affected users to upgrade to the latest versions of their browser, or make changes to disable TLS 1.1 and below.
Please use the following links to upgrade your browser:
Internet Explorer
Firefox
Chrome
Safari
Internet Explorer
Option 1 (Preferred) – Upgrade to the latest version of Internet Explorer at http://windows.microsoft.com/en-us/internet-explorer/download-ie, or Microsoft Edge at https://www.microsoft.com/en-us/download/details.aspx?id=48126 (Windows 10 only)

Firefox
Option 1 (Preferred) – Upgrade to the latest version of Firefox at https://www.mozilla.org/en-US/firefox/desktop/

- Select 'I accept the risk!' if you are shown a warning message
- Type security.tls.version.min into the search box.
- Double-click on the security.tls.version.min row
- Change the value from '1' to '2' (0 means SSL 3.0, 1 means TLS 1.0, 2 means TLS 1.1 etc)
- Click 'OK'
- Changing the setting will force Firefox to use TLS 1.1 or better
Chrome
Option 1 (Preferred)> – Upgrade to the latest version of Chrome at http://www.google.com/chrome/
