I know what you mean. When I sell on Ebay (not very often) I get hubby to work out the postage & he's very good at it. After allowing for packaging & the postage itself I break even on it. I wouldn't like to make a profit out of post & packaging as I don't think its fair. Hopefully your seller will get back to you & you can sort something out. Have you thought about mentioning it in the feedback if you are still unhappy about it.
