I have done business with Best Buy on a retail level but their Geek Squad keeps me coming back.
This is only one instance where they were outstanding. We purchased a laptop. It was brand new and we were not sure if we could competently install the new operating system and/or software. We were able to work out a deal with the purchase price and warranty so that installation was reasonable and guaranteed with DISKS.
We keep going back because of the service, openness, helpful staff and great atmosphere.
