Add shopping cart to website
We can add a third party cart or we can develop a custom cart. Third party carts are great because they have many useful features and functions. Downside is that not everyone needs all the functions available and so the admin can look a little complex. Also, third party carts can dictate the layout, making your site look similar to all others that use the came cart.
A custom cart is more expensive but it can fully match your business process and there are no restrictions on the layout.
