From my experience, as long as you adhere to the return policy (see e.g. walmartstores.com/7658.aspx ) you will be able to return items purchased in one Walmart store to another. In fact, according to walmart.com/returns you can even return items bought from Walmart.Com to a Walmart store (some departments may be excluded so read the page carefully).
If they sell the exact item, probably. Will only get the selling value that they are selling it for, not what your receipt says if it is from a different store. Will probably only get store credit also.
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.
