You clearly don't understand economics yourself or have never owned a business. The point is to always increase sales. It was reported months ago that Tim Cook would like to sell 50% of iPhones in their own stores. Best Buy is a Pawn for Samsung with more of their branding visible than best buy once you get inside. Even on their flyers. That is not the experience Apple wants their customers to have. In the Apple Stores they don't have to share the profit, and they can sell accessories, warranty upgrades, and Macs. This deal also get to sell the refurbished models for additional profit. At Best Buy Apple products are hidden in the far corner where only those who go looking could find them.
I'm inclined to agree with you on Best Buy. My experience is that BB employees make verbal misrepresentations to discourage sales of Apple products. The best one a BB staffer told me was that Macs are not good because "they have so many viruses".
I was only using the demo Mac to get info on a different location. The unrelated item I wanted was not in stock there. BB folks go out of their way to sell anything but Apple.
