Best Buy should just eat them.
Best Buy is going under themselves. Best Buy is essentially Amazon's display case. People go to Best Buy to get hands on with an item, then go home and buy it cheaper on Amazon and have it in 2 or 3 days at a much cheaper price. Best Buy isn't going to last very long either.
As for Radio Shack, they are a victim of the changing times. Years ago, you could go into Radio Shack, buy quality electronics, and if you ever needed service, you could drop off the unit, and Radio Shack would ship it, service it, and return it to your neighborhood store for you to pick up when it was done. This was very convenient when you considered that you had to pay for shipping both ways, and wait weeks longer to get equipment serviced for the major brand names. You also paid a premium when you bought the device because they alone offered this service. Also, they were the first to market with a home computer, and had the distribution system and servicing capabilities for computers as well. Over the years, as electronics continued to shrink, servicing became less needed as the electronics started becoming so cheap, when it broke, you tossed it, and bought a new one. Servicing equipment wasn't as needed or desired. So with the loss of the servicing business, they started servicing anything your dragged in, which destroyed the advantage of buying their brand name, and computers became such a low profit margin item due to competition from cheap PC makers that they sold off their computer factories and exited the computer biz entirely. They've always been a conservative company, and were late getting established on the web, which didn't help much, and they've tried to prop up the business by being a cellular dealer for all the major cellphone service providers, but there's tons of dealers like that out there, so while that helped, it's not carrying the business. They're also a victim being looked at like "Dad's" electronics store while the younger generation has looked elsewhere. Their recent Superbowl ad reflects that as they've attempted to re-image themselves as new and hip in a bid to attract younger users, but most younger users either get their phones through their parents, who generally go through the carrier directly, or buy prepaid crap in ghetto dealer shops that sell blunts, t-shirts and bongs. They've been on life support for the last few years, and they're going to run out of money soon. Their management is clueless at this point with what to do, their new boss wanted to re-image the stores and close a bunch of stores, but that's far too costly as re-imagine costs money, and closing stores involves buying out leases and shipping stock to other stores, so closing stores is more costly than one would think.
I think several years of bad management, and not finding ways to keep up with the times as their old core businesses became obsolete or unprofitable is why they're on the verge of collapse. I've already accepted that they're done. I'm just waiting for the doctor to come out, shake his head, and say I'm sorry, but they're gone.
Back in my day, we were business professionals, wore ties, and knew what we were doing, knew the product line, etc. A few years back, while servicing some DJ equipment for a friend I stopped in to buy about $40 worth of pieces parts that I needed, and the guy behind the counter offered to sell me the stuff cheaper if I didn't need a receipt. I told him I was doing work for a client and needed to produce a receipt for him, but the reality was that I was incensed that he was attempting to rip off the store. I knew the district manager from when I worked for Radio Shack years before, plus I grew up down the street from him, so I called him and gave him a heads up. Never saw that guy again...lol.
It's too bad, because as a kid, I used to go there with my dad to test tubes when our tv took a shit, and as a young adult, I worked for both Radio Shack and Radio Shack computer centers. I cut my computing teeth on a Model I and Color Computer 2 and 3, and have many fond memories as both a kid and adult. So, it's tough as I have memories that stretch back over many years, and it's sad to see they were so poorly managed the last 20 years or so that they're all but done at this point.
