I am looking for an easy to use shopping cart program (preferrably free/open source). The two most immediate choices are Zencart and Oscommerce. Which of the two would you recommend based on ease of adding items (I prefer mass import of items and my description and prices are in xls format) and obviously security.
Or is there another shopping cart script that is better (again keeping in mind that I am looking for a free/open source script).
Thanks in advance for your recommendations.
