That hasn't even hit American stores yet! You're in the UK, right?
Our Toys "R" Us stores are supposed to carry the Vintage Collection Endor AT-AT but so far none of them are on shelves and domestic collectors over here are being led to think it'll be a spring 2013 release. Right now we still have plenty of unsold Millennium Falcons and MTT Droid Transports in the aisles taking up space.
Congrats! I'd love to see some pics if you can take them!
