I think it is funny the seller is requiring bidders to have at least 50 feedback when he himself doesn't have 50 feedback.
His answer isn't very settling:
"Hello, I have two negatives only, the first one was miscommunication between me and a seller (and that was my first transaction so I wasn't quite sure what to do) while the second one was revenge from a seller with more than 2000 negatives that I negged for his awful communication and sending me damaged items after making me pay triple the shipping costs. I require 97+ feedback because that's what my requirements for my auctions are. Good luck and happy bidding. "
He requires 97+ feedback because that's his requirement. Laugh?
