I say it more to do with members using a recent link provided by HDN members and a recent 10% discount code you used with this link for the discount code to work
It's sort of noticeable as members who did not use the discount code had their orders despatched while those that did use this type of discount code some have been left waiting for their order of this steelbook and other different steelbooks to be despatched
Note
These orders are still despatched but are later than members who did not use the discount code
Recently it is happening more often than before when a link and discount code was used by some members and is usually the same link and discount code
Its strange as it dont happen as far as I know with members who did not use these type of discount code
I expect my order for this steelbook payment will be taken on Monday and will be despatched on Mon or Tue and that is exactly what happened just recently with some previous pre orders were I used a similar type of discount code
Not sure why Zavvi do this as they still take payment anyway and despatch your order even though it is later than members who did not use the discount code had their orders despatched
Example
My order not dispatched yet ? asked did you use a discount code and every time the answer is yes
Then a few days later your order gets dispatched
If this is just Coincidence then its very regular remarkable concurrence of events
