Recently eBay has increased cost of marketing through stores based on assumption their cost of hosting store listings is higher because of the store item salability. Perhaps it is truth in some cases and I don't dispute that however I believe that most webspace their cost is based on is occupied by images. Since all my images are hosted on my own server should I receive a refund as well as discount for future listings due to the fact it cost them way less to host my listings than it would be otherwise?
