COULD SOME SELLERS HAVE ADVANTAGES OTHERS DONT ?  I suspect ebay do look at the volume of business a seller has along with thier previous history. If thier scores for postage time & cost, item description and communication are in the 4.9,s with high pos. feedback scores and high stock turnover, ebay are more likely to treat them with respect than low turnover clients with average feedback scores. If these sellers can present a fair and reasonable case, ebay does tend to give them a pretty fair go. This does not excuse the sort of bad experience you have had and I doubt that ebay would act against you, had you not mentioned the dispute case in the feedback.
