You can make serious money from ebay if your idea is good enough. Always try and develop your idea in an area that hasn't been used previously. There is no point in congesting the market place afterall.
Once you know the items you are going to sell. Try it slowly, see what items sell and if they don't you may want to try at a lower price or simply remove the item straight away.
It is always a good idea to list items in your shop even if they do not sell elsewhere. The reason for this is that the costs is only 8p with a gallery picture every month. At 8p you can list this item for around 10 months and even if it only sells once at 99p you will get your money back !!!! If you sell 2 you will have a profit !
I sell excellent compilations of ebooks which could get you started in your ebook business and my prices are the lowest on ebay.
