I don't know if this will help you or not. The Grocery Game has weekly sales lists where the listing is green if an item is on the 12-week cycle's low point (or blue if it's free). This isn't a comprehensive listing of every item in the store; just the items that are on a good to excellent sale.
Really, comprehensive price lists would not be something other than management of those stores could have their hands on, and some of those prices change every day. There are industry spies that go from store to store, but usually with a small list of items to price. If store security spots them, they're escorted off the property.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
