I know this might be a noob question but how does it work exactly? I mean do I get credit as long as they click through my link? What if I send them from a link of a hair dryer and they buy a bunch of other stuff but nothing related to what i got them to click on? How long do I get credit for them going back in to buy somethin? I know I can probably read up on this on the amazonasociate site but I was hoping someone had a quick answer for me.
