it wasn't so much the way i was doing it ebay would start download then abort many many times then would flip from basic to advance from listing to listing was another problem, Maybe there system overloaded at times. Again 15% is a chunk of funds for what you are buying. But Paypal should make money for them in the retail space.
Try selling amy of your items at say an auction house -- IF they will take and sell your stuff with will collect from 20% - to 35% of your sales price! Try setting up your own brick and mortar store somewhere and getting any foot traffic, certainly it will cost you more than 15%... try and set up your own web site and get even a thousandth of a percent of the traffic in a day that ebay gets in just one minute .... you'll never do it ---- this is why you need eBay as a seller and why eBay/PayPal is so valuable
