They're finally bringing trading to the next level.
I don't really use jsp for trading these days but doesn't this remove the need of using tradelinks here?
Doesn't really remove the need for tradelinks. It would still be safer to use a tradelink to an item. Just means you can buy the item instantly rather then having to physically trade with the person.
They send the link, you click the link and instantly teleport to their house and buy the item. They send the FG after.
