I'm trying to figure out what you're asking. Do you mean if you reuse a link from an older order? If so, then, no, it won't carry over, far as I'm aware. It needs to give you what's called a session cookie, with the A2K account number, for us to get credit. The session cookie is automatically added when you go through the Home Page or through any of the Amazon links on the Portal. But it isn't otherwise automatically entered. If you go to
www.amazon.com by just typing it into your browser, you will not get the session cookie.
