Without these cookies, services you have asked for, like shopping baskets or e-billing, cannot be provided. These cookies can’t be switched off and they don’t store any of your information.

These cookies collect information about how visitors use our website, for instance which pages visitors go to most often, and if they get error messages from web pages. These cookies do not collect information that identifies a visitor. All information these cookies collect is aggregated and therefore anonymous. It is only used to improve how our website works.

These cookies make your shopping experience easier and allow our website to remember choices that you make (such as your user name, preffered currency), and provide enhanced features. These may be set by us or third party providers whose services we have added to our pages.

These cookies are used to deliver adverts more relevant to you and your interests. They are also used to limit the number of times you see an advertisement as well as help measure the effectiveness of the advertising campaign. They are placed by advertising networks or affiliates with our permission. They remember that you have visited a website and that this information is shared with other organisations such as advertisers.
