Although it looked like they were toast at one point, they're at least somewhat profitable and have something like $40B in annual revenue--although that's declined somewhat year over year.
Not sure on the rest of the appliances. Is an odd listing.
Personally, I very rarely go into a Best Buy. Yes, I might buy a TV or a major appliance there but those are very rare purchases. I might browse once a year to see what the latest wearable and Internet of Crap stuff is out there but I literally can't remember the last time I bought something at a Best Buy.
That is a very specific tradeoff; I would personally avoid getting a phone through a carrier if I can help it.
I also tried to get a new surge protector in the same visit and they only had 2 choices in-store, both of them were over $50 for no obvious benefit over a $15 one from target.
