I wanna know the name of open source application for "e- commerce "websites.
i built an e-commerce store with prestashop, it's easy implemented
We've used OSCommerce with good results.
Do you mean shopping carts? There are many, e.g. Oscommerce, ZenCart, PrestaShop, Magneto and many more. Why not to use Google or Wikipedia to find out? It's just a matter of typing your question and clicking the search button.
