ebay shipping charges

i think it is way out of hand on ebay,how sellers charge what they do on shipping,i look for  a specific cd,only to find out shipping is 6 dollars media mail!!!ridiculous!!i am a seller on ebay and i only charge 3 dollars for a dvd and that is first class shipping,most of the outrageous shipping costs are from stores,dont get me wrong its great to buy from an ebay store(i have one as well)another ripoff is that some sellers do not combine shipping which is even worse,if you agree let me know!!!
