At least 2 months ago, I went to www.svcompucycle.com and put some stuff in my cart but never bought it. Today I went back and that stuff was still in my cart. Here's the thing-in between last time and this time I formatted my hard drive, wiping out any cookies, temp files, form data, etc. I have a cable modem but not a static IP. I even moved. So how did they manage to uniquely ID my computer?
