Yes, it looks like they sold out ALL of the History of the Daleks sets.
I am quite surprised that History of the Daleks sets 3 & 4 sold out so quickly. They have been sold out since last week.
The sets were released in early November, I believe? Is it really possible those two new Daleks sets sold out in a month, while all the other sets are in stock?
I am holding out hope that GOGS1 gets more in stock, as I have been wanting that Dalek chase guard since way back in 2013 and fate has prevented me from getting it so many times.....
