Harry Potter Advertisment

Harry Potter and the Deathly Hallows. This was in sainsburys in south woodford. It was right near the enterance of the shop which suggests that they wanted it to get noticed. The way they have the number of days left to signify the amount of days left till the releasing of the Harry Potter, shows that they want the audience to know exactly when it comes out, so that they go and see it.
