As a former (but very short lived) employee of Best Buy a couple of years back I would not be surprised at all by this, if it was true. They are losing to online retailers in terms of product sales margins, so they try to make up for it by conning customers into "services", insurance plans, and trying to get people to buy stupid magazine subscriptions at the checkout.
I also remember a story from around the 360 launch of them offering a "service" to "update" your xbox 360 to have backwards compatibility for $30 or something like that (because when the console launched an online update was required for it to function properly in that regard.)
It's sad though, because they used to be one of the best electronics stores in the 90's. I don't buy anything from them anymore.
As far as "proud to be an American"....despite the fact that Worst Buy is based in the U.S., they are just an example of a soul-less profit driven corporation. You'll find those everywhere.
