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 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.
