Could be.
The brick and mortar retail industry is withdrawing into commodity stores like Walmart-Costco-SamsClub-HomeDepot.
Anything else is in niche stores like Gap-OldNavy-VictSecret.
Beyond that the internet.
So BestBuy is becoming an accessories convenience store like Radio Shack. Cases, adapters, printers, ink, batteries, parts etc.
Well, that's too bad. That means no service whatsoever! Personally, I like Best Buy and I've bought all my computers there since Gateway became a shadow of its former self. (I have a small network of about 10 work stations). I've also bought a refrigerator from them and received excellent service, even on the last day of my warranty. When I've bought the occasional computer from Sam's or Costco, there is nobody around to answer questions. Gateway was the best -- order on lin and pester their service reps for help. Once they discontinued (or heavily curtailed) the on line service, I might as well go to Best Buy. I've mostly had good service from them.
BUT, they get a lot of pressure from places like Fry’s and Microcenter. Not to mention sites like Newegg, Directron, and the Great Satan, Amazon.com.
