Zero value for you!
Some value for people that like to look at the product, have it in their hands, etc...the checking out part must be a local issue. As an opposite anecdote I have checked out at many Best Buy locations across the US and have never had a problem(even the shady ones). I actually love going to see some of the newer gadgets, but admittedly I have not made many big purchases there.
They also have a decent financing program(0% 24 months) that is great in these high interest rate times.
...I do love Microcenter though...and Fry's before it went out of business...now those places I could spend all day in.
