Ele funciona criando uma versão modificada do controlador usada para adicionar um produto ao carrinho. Ao clicar em 'Comprar agora', a ação do formulário 'adicionar produto' é alternada para o controlador personalizado, que é redirecionado para a página de checkout se o item for adicionado com sucesso ao carrinho.
