I've written parts of a shopping cart / checkout mechanism for an 
ecommerce site once (though admittedly not with Zope 3 but Zope 2). Do 
you have any specific questions? You seem to have the right idea already 
with sessions, etc. (though nothing in an ecommerce application nor a 
shoppingcart implementation requires a SQL database).

If I had to do it all over again in Zope 3, I'd most probably leverage 
the form data validation and form handler action mechanisms zope.formlib 
has to offer.
