I guess you can post in the sales thread and tell the seller to cancel your bid. I was selling here a few weeks ago and a bidder told me to cancel the bid. So I looked at the list of bidders and cancelled it for him/her. I believe the seller will have to manually cancel it for you. I don't see another way right now.
I have also this problem but i m seller not bidder One of the cheat guy have maximum bid and dont pay then after i m cancel bid but after cancel bid our selling tool like monthly traffic, page-views, earning section his hidden and also my last date of bidding not appears and sale are not close. can i cancel this ??? please suggest me
