I went there about 2 years ago. It was a graveyard. I just wanted a USB extension cable, and they only had one, and active extension cable that must have been languishing on the shelf for 10 years. What I don't understand is how best buy has survived and Frys (I think a much better store) did not survive.
- Beefed up their online presence. It's honestly a better experience than Amazon because it's specialized (which is a low bar, but still).
- Use stores as distribution centers. You can make an online purchase and then go pick it up that day if you feel like it, which Amazon struggles to compete with.
- Focus on customer service; both sales and Geek Squad. People who don't know exactly what they want will be lost on Amazon; Best Buy not only has people who will give recommendations, they'll even send someone to your house for free to evaluate your needs. Then after you purchase you can get in-person customer support (which can also go to your house if you want). Almost an "Apple Store for all the other tech products" kind of idea. There's an angle here, of course, but I think there's also genuine value for non-techies.
Contrasting the way they and Fry's responded to the e-commerce era is actually really striking as a case-study
