Zen Cart truly is the art of e-commerce; free, user-friendly, open source shopping cart software. The ecommerce web site design program is being developed by a group of like-minded shop owners, programmers, designers, and consultants that think ecommerce web design could be and should be done differently. Some shopping cart solutions seem to be complicated programming exercises instead of responding to users' needs, Zen Cart puts the merchants and shoppers requirements first.
