You might want to check to see if the existing listeners built-in to
Satchmo are affecting the behaviour.
Try creating your own listener by copying the code from
veto_out_of_stock, and then disconnect the satchmo listener:
signals.satchmo_cart_add_verify.disconnect(listeners.veto_out_of_stock)
Then connect your new listener
signals.satchmo_cart_add_verify.connect(veto_for_product_qty,
sender=None)
Also, be aware that depending on where you set up your signals they
may be getting called twice per request. I had that problem once..
