title: Building a wish list
body: <p>I have the task of building a wish list, where simply a user can add a products to a list.</p>
  
  <p>There are no user accounts on the site, so I am trying to find a way to do this without the user having to login.</p>
  
  <p>The wish list does not need to be remembered for weeks, just a few days.</p>
  
  <p>What method would be best to use?</p>
  
  <p>IP address?
  Sessions / Cookies?</p>
  
  <p>Any advice would be great. </p>
  
  <p>Thank you</p>
