If it's done as dgordon says it is, you can simply swap in an empty cookies file each time before going to their site and order as many as you like. Haven't tried it but it's easy enough to either clear your cookies, or simply pull the cookies file out of your preferences and with Netscape it will make a new one when you launch the browser. Then, quit your browser, throw that "magic cookie" out and put the old one in (if you want your old cookies) or start browser without any for a fresh start.
