In general, cookies are used to retain user preferences, store information for things like shopping carts, and provide anonymised tracking data to third party applications like Google Analytics (which allow the website owner to see which pages are getting the most hits for example).
As a rule, cookies will make your browsing experience better. However, you may prefer to disable cookies on this site and on others. The most effective way to do this is to disable cookies in your browser. We suggest consulting the Help section of your browser or taking a look at the About Cookies website which offers guidance for all modern browsers.
Good advice: If you log into important sites, such as your bank account, ensure you log out again when you have finished using it and close your browser. Don’t use other websites in that browser while you are logged into an important site like you bank. This is because if you are logged into your bank account on one tab another page could post to the bank system (in theory) due to your being logged in. Our use of Google Analytics is much less important to you, in our view.
