Ok here we go.... Want to pre-order new release blu rays, what is the best place to get them from? Hunger Games Avengers Assemble The Amazing Spiderman Prometheus Now I know the last 3 have special 3D editions, do they also include extras that the 2D versions do not? https://www.sainsburysentertainment.co.uk/en/Films-TV/Blu-ray/Robert-Downey-Jr/Avengers-Assemble-Sainsbury-s-Blu-Ray-Exclusive/product.html?product=E11108583 What is the sainsburys exclusive copy? Is it the artwork? Also the same with the Hunger Games, there is an exclusive sainsburys copy, is that worth getting over the others? Thanks!
