First of all, if you have never sold on Ebay I would recommend starting out with selling a few small items on auction listing to get some seller feedback.It used to be that you can't have a store until you have a certain amount of seller feedback but that may have changed.Paypal and credit cards are the only methods of payment allowed by Ebay. Sell all items as Buy Now which is great if you have multiple items that are the same but when you want to sell individual stuff on another Ebay account just sell it on auction listing.It is really very important to know what keywords to use to list your stuff. Cost of having an Ebay Store is about $15 a month plus listing fees which are not much when you list them in your store.Remember that store items do not get near the exposure that just listing on regular Ebay does. List everything as Buy Now with automatic relisting so unless something sells, you don't have to change anything with it.That is a good part. some months you can make a lot of money and others not that much. The total cost for you to have the store running on its own like this is about $60 a month including the $15 plus the relisting fees that happen as the items are automatically relisted, not much for something that runs itself and makes money.
