Just curious on your thoughts about putting bidding requirements on a listing, which I see someone else wrote about and the response was this could only be done through eBay. It is my understanding that you can block a bidder with certain level of negative feedback, etc. Does this have to be set up prior to posting listing. I have two bidders that seem to be battling it out with bids and one has a -1 feedback score and positive feedback of 49%! and the other a feedback score of 2 with positive of 66%. Would you recommend trying to remove these bidders or set up to have these kinds of bidders blocked. I'm still new, and certainly don't want to get burned especially on a big listing. Thanks.
