Why I don't shop at Best Buy

I don’t normally shop at Best Buy. Over the years, I have found Best Buy’s prices to be suboptimal and the sales staff to be ill informed. A while back, New York’s attorney general sued the company for having two websites with different prices. If you did a price comparison at home, you saw one price. But item in the store would be labeled with a higher price. If challenged, the salesperson would go to the internal website and show the customer the higher price. (Ditto if the customer used a smart phone connected to the store’s internal network.)
I thought that behavior had ended, but apparently not. I needed to replace the Nike+ sensor on my shoes. It’s a $20 item at the local Apple store and is supposedly the same thing at the local Best Buy down the street. Since I was going to the Target right next door, I stopped in Best Buy to pick up the sensor (http://tinyurl.com/klsjm6k). Whoops. It was $21.99 in the store.
The nice salesperson said it was probably a different model. Nope, it was the same MA368LL/B that Apple sells, that Staples sells and that Best Buy supposedly sells for $19.99.
It’s not often I see prices in stores higher than MSRP, but Best Buy seems to do it on the items I tend to buy.
I assume they do it on the other stuff, too, so I don’t shop there.
Best Buy. It’s just a name, not reality.
