I ended up leaving and buying what I needed on Amazon though. I had limited time in the store and didn't feel knowledgeable enough to choose between a handful of products, so I went home to do some research before ordering.
I wonder if Best Buy would benefit from a lounge, where you can sit down in peace, read product reviews, and browse online to make an informed purchase. Or maybe they could have tablets on stands next to groups of products with reviews. For example, you go to the printer section, and there's a tablet that shows all the printers and their user reviews. Then you can quickly compare options, sort by price, and see what printers are best reviewed.
Sometimes I try to check reviews in a store with my phone, but I usually feel out of place standing in an aisle for 15 minutes looking at my phone. So, it would be cool if they had a place where you could actually sit down for a while to educate yourself and make a decision.
