If we look at this thread with RJK wanting to say certain things but obviously being held back by certain agreements which forbid him to do so and we look at the dates involved we should have seen how this was going to turn out.
The game will be available to play as soon as the servers come on line after midnight Monday, so realistically sometime Tuesday morning. So for OCUK to get this expansion out to us in time they would have had to ship either Friday or Saturday, Saturday of course costing a premium from the shipping company so realistically that counts that out and Friday well that could be 4 days before hand if you were to walk into the shop to get it.
Blizzard and the distributors must work it out so that the what i can only assume must be several pallets full of the expansion arrives at the shop with no option but to only be able to ship the day before release.
What it all boils down to is that RJK did what he does so well, sold us a product that we wanted and are more than happy to buy, did he do wrong, no of course not. I expect he would have been happy to send them out earlier if it was possible but with distribution deliveries and street date agreements etc it just wasn't possible.
In the end thank you OCUK for saving me £20 on my 4 copies of &bucket 
as my son has been calling it.
This is not meant as a moan, just a little clarification for those of us who might be a wee bit peeved as to the way things have turned out.
PS. one thing I did notice RJK you said this was special preorder pricing and yet now you have them listed normally for the same price.
at least i wont have to go out in this rain now
