Best Buy quality check on open box items is ZERO. I have had two experiences now where an Open box excellent condition TV, had pixelation and picture skipping issues. The much touted Geek Squad is overrated, it's a bunch of tired geeks who don't like talking to people. This store particularly has terrible customer service.
I went in to get a new unlocked Android phone for my wife. The music was a bit loud for my old ears.
The place was pretty busy, so it took a while to get a sales person. Once I got one (however) he was quite efficient and knowledgeable, and got me a Galaxy A-16 in short order, and had me on my way.
Wonderful store! Great customer service!
