If you want to have an online store, then there are some things that you need to keep in mind. The difference between selling on eBay and having an online store is that if you have your own store, then you will have to look for visitors yourself. Ebay has millions of people visiting the site, so you will not have to worry about traffic, but if you have your own store, then you may need to advertise. However, there are some advantages of having your own store as you will not need to pay listing fees like it is in the case of auction sites.
