cartridge_stripe.forms.OrderForm: 'dict' object has no attribute 'iteritems'

[NOTtheMessiah]

When I click "checkout" the following happens:

ImportError at /shop/checkout/ Could not import the name: cartridge_stripe.forms.OrderForm: 'dict' object has no attribute 'iteritems'

This seems to be an issue from using Python 3 looking at https://stackoverflow.com/questions/13998492/iteritems-in-python/13998534#13998534
