The Really Useful Products web site uses a shopping basket facility hosted by RomanCart. As soon as you start putting items into your shopping basket, RomanCart will start using its own cookies to keep track of what you are doing (such as what items you have in your basket). Without these cookies the shopping basket would not be able to function, and you would not be able to buy things from the web site.
