Shopping Cart Help

I am trying to create a shopping cart in CodeIgniter, Could you guys suggest me any easy method that works perfect. 

Easy and works perfect?

That's the spec you're expecting helpful responses from?

Maybe consider shopify.
Or use Paypal buttons (the buy now ones)

But anything more than a simple single one-off transaction will not be easy - and - few things are perfect.

Recommend that you get an off the self Shopping Cart.

What did you Try? What did you Get? What did you Expect?
