You are missing something here.

There is a difference between waiting to get positive feedback from the buyer and waiting to hear they have received the merchandise and are satisfied.

Lets say you are a seller and you receive payment, you post positive feedback and then ship the chips. Immediately after you ship the buyer sends you an email calling you a thief because he doesn't have the chip yet. You know that it takes a few days for the mail to get from you to him and you mailed it immediately.

He now sends you an email every hour on the hour filled with profanity and references to your mother. He gets your contact info from Ebay and calls you constantly even in the middle of the night so that he can yell at you because the chip hasn't arrived immediately.

Has this sale been a positive experience? Would you recommend that other people deal with this buyer? Would you want to deal with him again?

Is that to extreme? how about this one. The chip arrives and the buyer is not happy with it. Because you are a CC & GTCC member you of course agree to a refund. You mail out the refund immediately because the guy has good feedback. He cashes your check but never returns the chip. And you have already left positive feedback.

But you have already left positive feedback so you can not leave the appropriate negative feedback. Feedback should reflect upon the whole of the transaction not just whether payment was sent.

I agree a seller should not insist on getting positive feedback before he leaves feedback, but I think he should wait until the whole transaction is settled.
