I have only bought and sold a few things on EBay , like just under 200, but I `ve always felt its the correct thing to do when someone pays you for your product (mine) that you then give feedback based on that part of the deal...he/she has fulfilled his/her obligation ,you`re supposed to give feedback on that part.... then its your/mine to live up to yours , delivering whatever you/I sold...then the buyer gives feedback on that part...
I know, many EBayers dont do this , you are/were? not the only one doing it "the other" way...but its not whats meant to be, "feedback"...
