It took 10 days to arrive not 5. Not waiting that long again I’m afraid. I can have stuff from the other side of the world in half that.
Feedback Response: Thank you for your feedback

We dispatch all orders (including yours) within 24 hours of receipt, but unfortunately we are at the mercy of the local postal service once it leaves us.  We do offer additional postage methods to guarantee a faster delivery.
