I will continue to get my "dose of HiFi" through reading online audio and video reviews, discussion forums, and then buying the products online. I have not once been disappointed with my electronics purchases performed online after doing thorough research first. I have not once been disappointed with the huge savings I have gotten from doing this. B&B retailers will never be completely gone, some people still need them as they require some in person guidance.
I have 19 speakers, two subs, two receivers, etc. The last major electronics purchase I made in a store was a yamaha pro logic receiver!
This frankly is no skin off my back.
