Music section: Best Buy and Walmart

Why was the information about the modus operandi of CD sales when it comes to Walmart and Best Buy removed? I think its pretty interesting that Walmart refuses to sell uncensored CD's at all but Best Buy doesn't sell censored CD's in their stores, and customers must go online and pay extra to buy a censored CD. I experienced this first hand recently at Best Buy, I noticed 2 copies of the same CD were different prices and I asked why; was one a special edition? and the guy said no, we don't sell censored CD's in stores, only online. It didn't matter because I wanted the uncensored version and I as glad I paid less. This might be original research but its true.
