Web components which convert any web page into a shopping cart.

This includes components to:-

• Dynamically update price and qty for listed items.
• Add items to a cart and manage cart.
• Authenticate and checkout.

Once customers are authenticated, price / qty shown and the types of payment / shipping methods available may change. This functionality is usually specific to B2B e-commerce.

For a website to use these components, it should include a single .js file and the appropriate components in the pages HTML.
