I've just used the code and it worked for me as well. For some reason, the delivery was upgraded to next day again, so my (very boring!) stuff will be arriving shortly.
Can you use the code to order from the PRO store? I need some eyeshadows but the pro pan refills are £7 each, and you can only get pots for |£10 each from the website
No because you can't order online from the PRO store in the UK. Only by calling the Pro order line and I'm not sure they will honour the free online delivery.
