Our experience might be a little dated at this point since we're not in there everyday making big ticket purchases.
First, we had a great experience buying a dishwasher there coming up on two years ago. We were just out shopping with plans to hit the usual suspects. A "kid" 1/3 to 1/2 our age helped us out and, boy, did he know his stuff about dishwashers! He walked us through all the models, pluses, minuses, worked within our budget and left us alone when we needed to chat. The experience was so good we bought on the spot forgetting about going elsewhere. Best Buy hauled away our old dishwasher and we did the install ourselves.
Fast forward a year and a half and since we had such a great experience with the dishwasher we went back to check out their TVs. We were already eyeing one at Costco, but wanted to see what Best Buy had to offer. Did not care for the salesperson this time around. My husband prides himself in the amount of research he does on all our electronic purchases and was lied to about the specs on the Costco TV. Plus they were pushing to sell us a much more expensive television. So, you can guess where we bought the TV.
As of last Fall, Best Buy recycled old electronics waste (like old tube TVs) for free. I am unsure, but they may be charging for this now based on a post I read in my local nextdoor.com forum.
