EBay, Collectors, Flea Market & Antiques

did you know that ebay makes almost 10% on the shipping charges..so if the buyer pays $20. to ship an item which actually costs $20 to ship, ebay takes 9% actually, almost two dollars. On every shipping cost. Trust me, that adds up. Yet the buyer can leave low dsr's for overcharging on shipping . Thats makes it tough because the buyers dont know. I dont see how ebay gets away with making a profit on shipping charges. I've called them over and over because as a collectible seller, I'm getting killed by them. Now I have 4 dings for overshipping charges and I swear, I don't make money on shipping and usually refund if they live in my state and it ends up costing less. However, 3 dings in a year, even if you have 250 perfect ratings takes away top rated seller status..which translates into a 20% discount on final value fees. Good for the sellers but since Sept, they started profiting on shipping..plus 10% and making it more difficult to get the discount..so there ya go, they get 30% more at the end of the month and I'm still working my tail off. I dont charge for packaging materials but Ebay says just build those costs into the price but that's bs..at least for the things I sell. How do you raise your prices when people are struggling?
