It's important to ready privacy policies so that you completely understand how your personal information is being used and protected. For example, if you purchase a product, you must reveal your credit card number as well as other personal information. Does the Web site have security measures in place to prevent someone accessing their servers and stealing their data?
Even if you aren't going to purchase products from the Web site, you may be giving up personal information simply by landing on their home page. It's not uncommon for IP addresses to be collected and recorded. While not necessarily personally identifiable, some users object to this.
