I have never sold anything on e-bay before, but I have some audio gear that is just sitting around doing nothing that I figure I could get some cash for. I have an e-bay seller account setup and everything and I am sure e-bay takes you though a lot of the process. But could anyone give me a few tips. For example I am not sure what to do about shipping, do I need to figure out how much it is going to cost to ship my product and then post the shipping cost in the auction, or can the buyer contract and discuss it with me? Any experienced sellers have an advice for me? Thanks.
