Buying in poe.trade

Hi guys i just want to know how can i buy on poe.trade?. When i message the seller there is some stash tab position left, top etc. I'm confused, can i access the seller tab then get the item like that? I pm'ed almost 10 people and no one's reply, but their online.

No, you cant access the sellers stash in any way. Unfortunately, you'll have to wait until a seller has replied to you or invited you to a party. Once that happens you usually travel to their hideout and then accept their trade request (or request to trade the player if they haven't already done so).
