absolute newbie question

so, i have been lurking this site for quite a time now, only recently have i decided to buy a razor. but i have a question. what does the "contact seller" button do? does it send a email? a PM? I'm only asking because none of the sellers i contact answer me back:(
thanks

go to the persons info page, simply clicking on his name then "view public profile" then ... http://qkpic.com/243e7

also give it some time till a response, maybe they simply don't get around to it.
cheers.

Cool. thanks for the fast response!
