" I wonder if you would buy from a seller with a 98.6 rating?"

Wonder not...I certainly would...after looking at the negs...which quite often are inaccurate & left by clueless buyers.

" It is courtesy on both sides."

Oh I agree...but on this site it's still voluntary.

"You don't understand the obsession with feedbacks?"

That's right I don't...particularly when a member has received  let's say as an example 1120 & left 1053.

" Much ado about nothing. Really!"

Yes really...I have no beef with the feedback system...I leave it for every sale & purchase...but I certainly respect the right of those who do not choose to do so & do not worry if I don't receive any...I understand the meaning of voluntary.
