There's no 'Save For Later', and there's no 'Empty Cart' or 'Discard Cart'.
While carts are never removed from the database, they are discarded
after the gateway reports acceptance of the payment:
@cart.user_id = nil
@cart.save
session[:cart_id] = nil
session[:order_id] = nil
Currently, this is the only way a cart gets discarded. That's a
problem probably most easily fixed with an 'Empty Cart' link or button.
If I add this, then if a user is signed in, I can give them their
most recent cart only if there is no cart pointed to by the session.
No cart is lost by signing in, and if they don't like the contents of
the cart, they can discard it.
Out of several alternatives, that changes the operation of the site
the least, I think. The status quo is no good, though.
