When your transaction as a buyer or seller on Ebay becomes successful or unsuccessful you are supposed to leave feedback. When you are a low end buyer or seller you want feedback for being a prompt buyer or seller. But with those with 1000+ feedback ratings say they want feedback, but they will only do it when people send them feedback it seems just to be an empty promise. I think mega sellers should have a bot to help them send feedback to their good customers.
I will never send any feedback to any power sellers until they realise they need to give the little guys some respect.
