Shopping Cart in PHP

This project is for a shopping cart written in PHP. We have an existing web site which needs a shopping cart but there are some conditions which must be met. See the detail conditions in the requirement section of this project. The coder is responsible to collect all the UPS shipping calculation needed for this project from their web site. As well as the FedEx. The coder would be responsible to provide detail instruction to implement this program with our existing project. Only after the implementation is successfully done and all the source codes are submitted to the buyer, the project would be considered complete and close. Once the project is completed the buyer would be the owner of the complete copyright of the code, design, and any related files and information.
