Good to know, RE: WB Shop, as it's my first order with them.
Do we know the number of Collector Editions made for release? Every retailer sold out quick and then by magic places like Amazon, Entertainment Store and HMV started selling more copies a couple weeks later.
I am very certain that Entertainment Store was still selling 10s copies the other day. Made me think there isn't a specific number of copies and they decided to sell as much as they can before the cut off date to have the packages manufactured. I'm highly likely to be wrong here, but made me think that whilst keeping an eye on stock that was still for sale.
Amazon/Entertainment/HMV have live stock system
When a customer cancels an order it lists back as available on those websites shorty after as in seconds/minutes but sometimes can be a few hours later
Amazon it's very quick when it happens
This why you often see when someone post in thread or you been checking website yourself see as back in stock and then quickly after back to sold out
Example if I was to cancel my amazon order (Which I won't be doing) it would show back as available very quickly and then someone who checks amazon website would see as available
Zavvi don't have live stock system they manually put back on system after customer cancellations are done this they do most times after release date but rare times is before this
You will see this show up again on Amazon/HMV/Entertainment closer to release date or after as more customers cancel an order for various reason or retailer cancel due to payment issues or security issues
Some people do orders from multi retailers around same time and closer to release date decide which retailer they keep their order with and cancel orders done with the other retailers
Some cancel orders at various stages before release date or wait just before release date
Example you had pre ordered on all or some of the retailers WB Shop/Zavvi/Amazon/HMV
WB Shop and Zavvi often take payment before other retailers you then decide to cancel Amazon and HMV orders and then that stock show's back as available on those websites
Print Run of the collector edition only Universal could give you that answer and unikley would tell you anyway
Sometimes they make it public the print run but not always
