I visited my local TRU store (Portsmouth) at the weekend and saw a box of Hoth Wampa Cave sets just waiting to be put out. Others are reporting more of the sets as available too, including (with reported prices) :
8096 Palpatine’s Shuttle – £59.99
8089 Hoth Wampa Cave – £34.99
8097 Slave I – £79.99
8129 AT-AT – £99.99
The AT-AT is the only one that has appeared on the TRU website.
More news on UK availability as and when we get it.
