I have sold on ebay for 4 years now and my fear is that if you dont allow the seller to have the option to leave feedback , many buyers will hold all the cards ..They will be able to renegotiate sale price after they buy an item or items ...that will be time consuming and frustrating to sellers ...This is clearly unfair and it will defiantely happen..eventhough my experience that a big majority or buyers are very nice and honest , there is a percentage of scammers , trouble makers and miserable souls that have nothing to do but to bring down a hard working seller .NOTE : A 99.3% FEEDBACK is a decent feedback score anything below is considered questionable and less trustworthy...buyers will learn this and the abuse will be multiplied ...Ebay has never ever done anything that didnt suit their bottomline . All the sales were strategically places on days where they knew would be slow etc etc
