Sanity check A good way to find out, if your product is as hot as you think it is, to check if somebody offers it on Ebay already. Search for it on the web, and pretend, you are the one that wants to buy it. This way you can see availability, price range and possibly even quality of what is out there. Needless to say: You will always be more optimistic about your own product than anybody else. You will be sure, that your product has advantages over the other products out there. So here is your first assignment: If you do find out that there are advantages of the product you offer: Make a list of these advantages, and mention them on your web site!
