OpenCart - Open Source Shopping Cart

OpenCart is an open source shopping cart that is built with PHP & stores the data in MySQL. The application has every standard feature an e-commerce website may need like:

• Unlimited categories
• Multiple images for products
• Customer reviews
• Multiple currencies & more.

OpenCart’s front & backends can be expanded with modules (there are already more than 30 modules). It has also support for:

• Templating
• Multiple payment gateways
• Multiple languages
• Various shipping methods (like weight based shipping) & more.

The open source shopping cart system can be managed with an easy-to-use administrator panel where all the orders can be viewed, products can be defined, etc.

A very nice feature OpenCart offers is the "coupons" where discounts can be set on a "per product" basis. There is also another open source e-commerce project named OpenCart Zero which is derived form OpenCart.
