Right I have just spoken to a lovely, lovely lady at Murad.
She went into the order system for me and was a bit taken back by the sheer amount of orders they received yesterday 
I gave her my order number (from logging into my account on Murad) and she found my order and re-sent my email confirmation.
She stayed on the phone whilst I checked it had been received...But it didn't come through. She said do not worry, they have the order on the system, the payment has been received and an email should have come out but the system is a bit overwhelmed by the sound of it.
I said I had doubled up on codes and she said they normally only accept one but because they are magazine codes you can double up.
I also asked if the book would be here by Christmas (didn't want to say sod the book give me my freebies!) and she said depending on Royal Mail orders should be received by the end of the week!
A really, really lovely woman with fab customer service skills.
I say we just leave them to work through the orders they received and take it up at the end of next week if nothing has been received.
