title: Magento Multi-Store - Cart Contents Issue
body: <p>I have a Magento CE 1.8.1 "website" with multiple "stores" on different domains.</p>
  
  <p>We are already using the SessionID in the URL to switch between stores. We have SSLs in place for all the stores that are currently live.</p>
  
  <p>The issue we are having is keeping the contents of the cart for a customer who is not signed in or does not have an account when they switch between stores without using the SID or if they visit one store, leave the website, and navigate to another store manually.</p>
  
  <p>Is there a way this can be solved? I know cookies do not allow cross-domain storage and am hoping to find a fix without paying too much.</p>
  
  <p>Thank you!</p>

  <p>-----EDITS-----<br />
  1) Here are my Session Cookie Management for the WEBSITE - all stores are set to follow config default:<br />
  LIFETIME: 5400<br />
  PATH: (empty)<br />
  DOMAIN: (empty)<br />
  HTTP ONLY: YES<br />
  RESTRICTION MODE: NO<br />
  <br />
  My store is setup with 1 (one) website and 4 (four) stores. Looking at my "Websites" tab in any product the result is this: <a href="http://i.imgur.com/fWFgSwb.png" rel="nofollow">PRODUCT WEBSITE SETTINGS</a></p>
