What is a good shopping cart gem for Rails?

ruby, ruby-on-rails, ruby-on-rails-3

Solution

There is a wide range of payment and eCommerce gems covered at Railscasts.

A list of gems can also be found at The Ruby Toolbox and here too.

Also, not covered, you can use the Saas product Shopify

Problem

I want to implement basic shopping cart functionality in my Rails app....are there any good gems that will make this process simple? i.e. I want the shopper to be able to add products and quantities to their checkout, and I want the admin to be able to add new products to the store (and edit/delete existing ones). Suggestions?
