To do this, we use 'cookies' or alphanumeric identifiers that we transfer to your computer's hard drive through your web browser to enable our systems to recognize your browser and to provide features such as storage of items in your Shopping Cart between visits. We use a third-party service provider to serve ads on our behalf across the Internet and sometimes on the Sites. This provider may collect anonymous information about your visits to the Sites and may also use information about your visits to this and other Web sites to refine our services. If you are concerned about cookies, the ""help"", ""options"" or ""preferences"" functions on most browsers will allow to limit or disable cookies altogether. However, cookies allow you to take full advantage of our interactive features, and we recommend that you leave them turned on.
