On day one when the non negative feedback went into effect, I received 3 negatives over a rediculous conversation of combining the 3rd item into an already combined 2 item checkout. Once it was taken care of, the buyer emailed some snotty remark that see if you would have combined all 3 items in the first place, you would not have any trouble. 3 weeks later at 6:30 AM on opening day of no negative feedbacks, she gives me 3 negatives. I was furious. I came back with positives with negative words that this person was a no good buyer. Beware of this nasty person. She complained to ebay and my DSR's took a drop. Nothing I could do and they erased everything I said about the buyer, but left what she had to say about me intact.
So do not do it!!!! Just play the ebay game until the end, yours or Ebays. I'm in there until Ebay is trumped by someone else. Believe me someone else is going to trump Ebay and they know it.
