I used to shop at Best Buy all the time. It had good deals on electronics items and had great service. Then the internet came around and I found out that by being your own sales representative, you can find better deals.
Normally, if I can't find my research on an electronics item on the internet, I will go to Best Buy and find out from knowledgeable sales people who have been trained for this. Otherwise, I will probably buy from cheaper sites on the internet and not have to deal with anyone.
