Information gathered through cookies and Web server logs may include the date and time of visits, the pages viewed, time spent at our Web site, and the Web sites visited just before and just after our Web site.  We, our advertisers and ad serving companies may also use small technology or pieces of code to determine which advertisements and promotions users have seen and how users responded to them.\n</div>\n<h3>How Do We Use the Information That You Provide to Us?</h3>\n\n<div class='info'>\nBroadly speaking, we use personal information for purposes of administering and expanding our business activities, providing customer service and making available other products and services to our customers and prospective customers.

When you visit a Web site, that site's computer asks your computer for permission to store this file in a part of your hard drive specifically designated for cookies. Each Web site can send its own cookie to your browser if your browser's preferences allow it, but (to protect your privacy) your browser only permits a Web site to access the cookies it has already sent to you, not the cookies sent to you by other sites.

For example, some of our partners operate stores or provide services on our site, while others power offerings developed by us for your use. We may also use third parties to facilitate our business, including, but not limited to, sending email and processing credit card payments. In connection with these offerings and business operations, our partners and other third parties may have access to your personal information for use in connection with business activities.
