I will defend sellers (just a little). There is a glitch (or purposeful shady code) in how eBay calculates some shipping costs. When I sell, I put in the weight and box dimensions. Folks on the West Coast, I am on the East, were regularly accusing me of outrageous shipping costs. eBay was quoting them well over $30 for shipping a single 1/25 scale kit. When I would plug in the exact information directly to the USPS site the cost was closer to $15. They are using weight and dimensions when calculating postage, so you are also penalized for using an oversize box and shipping safely.
