ebay madness. Cannot leave bad FB

I sell lots of stuff on Ebay. I don't leave a positive feedback, till the customer is happy and leaves me one. Out of 5 items I sell, I get 1 positive, so I won't leave any one something till they leave me one.I work hard for them (I have 440 all positive feedbacks). If they are not kind enough to leave me a feedback, after I bust my butt for them,to pack it nice, and ship it ASAP, then I am not doing them the favor either.I have sold stuff, and sent them double items, and even extra stuff, and don't even get a thanks.I have tried it both ways and this works best for me.
As for Ebay, it bugs me in so many ways, even after all the costs of about 17% (including making money off the shipping) It is still good, because I sell so many things that would just sit around, and nobody would buy local.Also, I find everything I want on there, including the Valiant I have, and all the parts I used to build it.
But we will see how they treat us in the future. Others have started similar sights, but they are not as good.
I do agree, dead beats get away with lots of stuff. It is to the point of picking the person with the least negative to buy from.That is sad. And worse yet, they are rated really high, because they sell so much and have so many positive feedbacks.You figure some may miss the mark a few times, but 30 in 1 month and 15 more neutral to me is bad, no matter how much you sell!
