In the US, ebay gets 10% of the total price, including the postage cost.I despise the GSP. I have bought a couple of items from buyers who only use that system because they don't want the hassle of filling out forms and shipping it themselves. In addition to the high costs they use FedEx and I'm never home when they deliver and have to muck around making alternative arrangements rather than just picking it up from the PO. Like you fuzzymummy I have cancelled transactions because sellers didn't realise they were locked into the GSP and when they called ebay they get this load of bs about how it's safer and it makes it easy for everyone because all charges are covered and the buyer won't have to pay customs etc. I buy all the time from the US and UK at the cheapest possible shipping even if I have to wait longer for it, and have never paid anything extra and have never lost anything. It's just another way ebay makes money, like encouraging sellers to do free postage so they can get their 8.99% on the postage as well as the sale.
