It's no secret that BB is competing with the entire planet via the internet on sale price, so perhaps BB should leverage it's brick and mortar advantage through it's Geek Squad services.
Position Geek Squad as the only source for service and advice - hardware, software, internet, phones, etc. Offer check ups, servicing, transfer of files, email setups -- any and all services the technically-challenged consumer will need at loss-leader prices to change the consumer's behavior and thinking about BB.
Expanded in-store presence, free help lines (phone and web) -- become the recognized expert and "Best Friend", there whenever a problem arises... and also there whenever the need for a new computer, phone, camera, software, game, mobile service, etc. is needed. Plain and simple ADDED VALUE.
Don't limit the give-away pricing support to only products purchased at BB. If "promoted" properly, that next consumer's purchase and al future purchases will be from BB.
Think of BB's Geek Squad as the Butterball "Turkey Hotline" for all electronics.
