Found 15th Dec 2016
Just spotted a few (bout 3 for each system - Xbox One and PS4) Lego Dimensions Starter Packs in my local Asda in Chesterfield. Someone might be able to grab a bargain for Xmas, I didnt pick one up as ive just started my lil lad on Skylanders. (its the Asda on Sheffield Road near Halfords). Sorry ive no idea if its national.
