How we use Cookies

What is a cookie?

Cookies are small information files used by websites to distinguish between individual computer terminals so that the pages and functionality of that website can be correctly and securely delivered.

Cookies are fundamental to providing user-friendly online services. The most common functions of e-commerce would be impossible without cookies.

There are two types of cookies that can be used in the Internet that you should be aware of – Session cookies and Persistent cookies. You can read more about these (and how to switch them off) at

Session cookies are deleted when you close your browser and are usually not saved to your computer’s hard disk. Session cookies are used to:

  • hold some types of non-private information you provide while using an interactive tool on the website
  • identify that you have logged in to the site
  • hold your search criteria while you are carrying out a search of the website
  • collect anonymous information on website usage to improve the site and service

Persistent cookies remain on your computer for a specified time and so are saved to your computer’s hard disk. Persistent cookies are used to:

  • identify that a registered user has returned
  • securely remember your login User ID – if you have asked to do so
  • understand how you use our site and obtain information on website usage

Google AnalyticsIdentifying Unique VisitorsEach unique browser that visits a page on your site is provided with a unique ID via the __utma cookie. In this way, subsequent visits to your website via the same browser are recorded as belonging to the same (unique) visitor. Thus, if a person interacted with your website using both Firefox and Internet Explorer, the Analytics reports would track this activity under two unique visitors. Similarly if the same browser were used by two different visitors, but with a separate computer account for each, the activity would be recorded under two unique visitor IDs. On the other hand, if the browser happens to be used by two different people sharing the same computer account, one unique visitor ID is recorded, even though two unique individuals accessed the site.
