people over charge on shipping on eBay, because eBay and PayPal only take their fees out on the auction price. they get 100% of what they charge for shipping. i forget the rates now, but lets say 2%. you sell an item for $100 and yo charge $30 shipping, you get whacked eBays insertion fee, then 2% so now your profit is down to $98. then paypay gets a whack out of it and then your profit is down to $96 (not going to get a calculator and get down to the penny) so you end up making $126. before you go and ship the item that cost, lets say $5 to ship. then you make another $25 not attacked by any fees. they don't take any fee's from your shipping. it just a way for people to combate their profits getting sucked away. but then in-turn they lose business because people don't want to spend way more than they know it cost to ship an item. but now they are trying to charge an internet tax on ebay sales, so there is another thing that will kill you.
