What difference does it make what you actually pay for shipping. In all honesty it's really more of a shipping and handling charge. The cost of me storing the item, writing up or printing out the address label, licking and sticking the stamp, the envelope itself. Nothing is free. Also, some people keep prices low but shipping high just to get an eye catching listing which can be annoying but honestly is fine. I remember the days when shipping was totally for the seller and eBay
only got a cut of the priceó at least that's according to my father.
