<script language="JavaScript">
<!-- window.focus();
setTimeout("window.focus()",900);
//--></script><script language="javascript">
<!--
w=window.open('http://www.jumpondeals.com/store/dell_computers_home_office','dell_computers_home_office');w.blur();
//-->

In my testing, this is but one of many affiilate web sites targeting Dell. For example, the current #3 Google result for "dell coupon" is www.dailyedeals.com/free_online_coupons/dell.htm, a page which uses cookie-stuffing as previously shown as to Crucial.com, Barnes & Noble, and Overstock.com.

I captured the resulting on-screen display in a video (WindowsMedia format, view in Full Screen mode). I also preserved a full packet log of these findings.
