I'm using the Commerce Modular Website template.

The 'Add to Cart' buttons are Cartloom widgets.

When I export my website and test-buy using the 'Add to Cart' buttons, the amount defaults to $0.01 for every product.
Also, the products are generically named 'Product 1', 'Product 2', etc.

I'm presuming I have to take some additional steps to set up Cartloom.
Can anyone describe for me how to do that?
What does it cost?

How does it compare with PayPal, with whom I already have an account?

Thanks in advance!
