title: How should I store shopping cart items?
body: <p>I'm writing a simple shopping cart in PHP, but I'm not quite sure how I should store the items a users selects to purchase. Should I use cookies? Of course, if I did use cookies, all I would store in the cookie is the item SKU and quantity. I wouldn't store the prices in the cookies, since the user could potentially change them.</p>
  
  <p>Thanks for your advice!</p>
