The way ebay is calculating the fees on promoted listings are evil , ebay is just letting sellers with the lowest possible profit, this is not fair for sellers and buyers, ebay's greed is worst every year. While they should be calculating the promoted listing fee only to the base price of the item, they go beyond that and calculate it to the final price including taxes and shipping costs, that's amazing seeing how they take advantage on everything only for their own benefit. sellers and buyers are struggling to offer and get better prices, at the same time we're competing against amazon and walmart, so we hardly can expect to get decent profit margins. Honestly I do not see a good future to ebay market, ebay is making their own business disappear , maybe they're squeezing the last drops from what years ago, was a great business.
