First ideas for research and development my project

I will start doing my project by collecting newspapers and articles online about the price war, which is going on between the big 4 supermarkets in the UK: Tesco, Asda, Sainsburry's and Morrison.

I will also interview some consumers among these supermarkets to find out whether they find themselves benefiting from the price war or not
 

First idea for project title

"What are the causes and consequences of the supermarket price war?
