Why does my shopping cart remain empty when I try to add an item?

Our shopping cart functionality is based on "cookies" or customized pieces of information our site stores on your hard drive. Because cookies only contain text, they cannot transmit a virus or damage your system. They cannot gather information about you or your computer. When you can only add one item to your shopping cart, it is usually because your web browser is not handling these cookies properly. In most web browsers (e.g., Internet Explorer, Firefox, Safari, Chrome, Opera, etc.), users have the ability to enable, disable or restrict cookies.
