jQuery: create a shopping cart with sessionStorage and PayPal payments

I've built this shopping cart after completing a web project where I had to rewrite an entire e-commerce cart. This project also includes PayPal payments.

This is a proof-of-concept and is not intended to replace any existing server-side technique.

Bear in mind that there are a few things you need to change on the main jquery.shop.js file, namely:

• The type of PayPal cart and its variables.
• The business PayPal email address.
• The URL of the PayPal form.
• The way shipping charges are calculated.

Hope you find this useful.
