Some sellers do not list s/h because they do not know exactly how much it is going to be(true), but some other sellers abuse this. I have won some CGC comics for really cheap, so the seller tried to mark up on s/h to make up for the final auction bid price. I believe that is horrible! EBAY should make it mandatory for sellers to post s/ h costs. I sell stuff on ebay all of the time. You can atleast estimate s/h costs, you don't have to be a rocket scientist!
