Most web browsers will provide the option to turn off or disallow cookies. How you do this depends on the web browser you are using. Instructions for disallowing cookies can usually be found in the browser's 'Help' menu. Note that in common with most other transactional websites, if you only disable third party cookies, you will not be prevented from making purchases on our websites but refusing the cookies we have used via your web browser will mean that you are unable to make a transactional purchase on our website. You may also find that the functionality of many other websites and services will be affected. Cookies can be deleted using your web browser. However, unless they are disallowed they will be re-applied the next time you visit a website.

If you want to disable cookies you need to change your website browser settings to reject cookies. How you can do this will depend on the browser you use. Further details on how to disable cookies for the most popular desktop browsers are set out here (these may vary depending on operating system and browser version):
