Best Buy effectively subleased a significant fraction of space, to an appliance store called "Pacific Sales." We have purchased such appliances there.
On TVs Best buy is price competitive, and I have bought some there.
Finally on cellular phones, BB has the major firms in house, and we have bought from them.
We have a multitude of choices. Fry's, Micro Center, Walmart, but BB has the best merchandizing,, the best website, etc.
Plus their sales people are salaried, not commission. I hope they survive.
