I don't ever recall getting anything that had to be returned to wal-mart aside from my own personal preference or manufacturing issues and I've bought A LOT of electronics from them.

Obviously I can't hold them accountable for my own likes and dislikes nor can I hold them accountable for a piece of equipment that doesn't work properly. I just return and get a new one and life goes on. Now if they manufactured the stuff that doesn't work that would be a different story.
