jQuery: a shopping cart with sessionStorage

I've built this shopping cart after completing a web project where I had to completely rewrite an 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 techniques.

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's cart.
• Your business email address.
• The URL of the PayPal's form.
• The way shipping charges are calculated.

Hope you find this useful.
