As someone who has been mainly a "buyer" up until now, can I say that I have found some amazing bargains at $5.00, and also made some purchases at $30.00 where I may as well have flushed my money down the toilet. As most other people have been saying, your product may be similar to someone else's, but if you throw something in that is unique, it might be that very something that pushes a buyer in your direction instead of the other person's. When you do finally release the product, make sure that you are available to your customers. I have purchased quite a few things from the Marketplace, but in a handful of cases was very disappointed when I went to the trouble of contacting the creator (both IM and EMail), but got absolutely no response. That puts me off buying anything else from them.
