1)Create something new that is at least a smidge original or top of the market.
2)Spam the forums with every post by putting advertisments in your signature.
3) The more people who know about your product, the more sales you will get. If you give your product away to friends, customers or enthusiast, they will bring sales to your shops. You kill 2 birds with one stone. You can throw bones to your good customers and show some appreciation, andmaybe get new business in return.
