I have a paintball gun that I want to sell on ebay to get a 1st gen iPhone but my parents dont think I know how so they want to take it to an eauction place down the road but I know that they take a percentage of that money and I need every cent I can get. Answer1:Very easy. Go to their web site and open an account. Requires some basic information. Then open a PayPal account so you can receive payments online. Then their tutorial will help you list your products to sell. I would go to the library and get a couple books on selling on Ebay and do some basic research. Great opportunity to make some extra cash.
