To make your developed theme or plugin a success, we need to have a good sale of our product. What may be the better proof of the triumph of our designed theme or plugin than better sales statistics along with positive impact and name? If we are a developer then we always try to get good deals for our products. For this purpose, there always required some best market places to sell WordPress themes and plugins.
Generally, it is difficult to deal with the market or spread your product. It takes a lot of hard, a good experience and a great network to sell such products. We may be able to expand our website but only to the tiny mass of the audience resulting in bad sales.
