Hmm, mine was marked as posted on 22/11/11. That's only 12 working days out of a possible 20 they state in the description.
As I purchased mine on the 17/11/11 so have roughly until the end of December to raise a dispute with PayPal.
If I don't get mine by the end of next week I will email the seller. If there is no response I will be raising a dispute with PayPal.
But hopefully it is real!!
