Whos job is it to contact for auctions? So I'm wondering, who's job is it to contact, buyer or seller? I've seen too many instances where people forget to contact each other and the auction never goes through. most likely it's up to both people, but what if they send a PM once telling you to "get on now" when you can't and then you tell them you will be on at certain times and they never respond and then they leave negative feedback.
