Essential Contributions for osCommerce

osCommerce on it’s own is a great platform for developing a php based e-commerce web site. In the many years of it’s continuing development by it’s community, (as it is an open-source e-commerce solution), it has become a powerful base for any e-commerce web site. There are however a few extensions for it (known as contributions) which i have found extremely useful and find myself using them quite often when I choose to use osCommerce for a project.
